I've been using unison 2.9.1 for a while now. It recently stopped working. When I fire it up in gui mode it allows my login via ssh to the remote box. Right after submitting the password I get an "Uncaught exception Gpointer.Null" error. Unison runs in text mode fine. I have run revdep-rebuild. I have re-emerged glib,ocaml,lablgtk,gtk,unison, and more packages with no avail. I've even tried upgrading to the lastest version of unison, 2.13.6, still got the same error. Also, I've tried logging in as a different user. Reproducible: Always Steps to Reproduce: 1. 2. 3.

Have you installed xorg-x11 6.9 or 7.0? I dont know if it is directly related, but when I installed xorg-x11 7.0rcX (?) unison stopped to work. Maybe it was something different, but since it works fine in non gui mode, it looks a little bit like that. PS: I tested unison 2.17.1 and it is the same.
You may have something there. I'm running xorg-x11 7.0 and it was working with the some of the earlier 6.9 releases.
I don't know if this helps but Unison's gui does partially work. I usually call unison with "unison $HOST" preventing the initial dialog for the profile selection. The "Uncaught exception Gpointer.Null" error shows up when it starts determining the changes. If I call unison without specifying the host the gui comes up and allows me to select the profile and enter my password. Right after that is when the error shows up.

I have the same problem now with unison 2.12.0-r1 after upgrading to Xorg-7.0-r1 The behaviour I see is the same as described: any initial dialogs work ok, but when the main program window opens it crashes with the Gpointer.Null error. I also have tried to reinstall unison, ocaml, and lablgtk, but still see this error. The owner of this bug should mark it as a blocker for bug 112675.
Investigating this further, it turns out to be the same as bug 121447 and is due to missing i18n libraries in X caused, I believe by a missing configure flag in the libX11 ebuild. It is the libraries in /usr/lib/X11/locale/lib/common that are missing.
I take back my last comment. The i18n library issue appears to be unrelated.
The real problem is a missing font. Either unison should depend on: media-font/font-schumacher-misc or that package should get pulled in by the xorg-x11 meta-build.
media-fonts/font-schumacher-misc seems to have fixed it for me. I had to restart X but Unison is working again :) Thanks!
Nice work! It should really depend on media-fonts/font-schumacher-misc
And one more confirmation that media-fonts/font-schumacher-misc fixes the issue, this time with net-misc/unison-2.17.1 and x11-base/xorg-x11-7.0-r1. I would make this a RDEPEND of unison in any case, to be on the safe side. Could of course ba an || dep to allow for the monolithic X builds as well. As the modular X is now released to the general ~arch public, this bug here becomes more urgent. I still have to figure out the reason for repeated connection loss, but I suppose this is unrelated - as long as noone else experiences the same after this fix.
(In reply to comment #13) Also solves the problem with unison 2-13.6 and xorg 7, but you have to restart the X server first...
Yes ! media-fonts/font-schumacher-misc have fixed it for me too :)
Same here. Whith more and more people migrating to modular x, this really should go into the tree.
same problem here xorg-x11-7.0-r1 unison-2.13.16 after emerge font-schumacher-misc-1.0.0 and xorg restart all is working fine. regards the2nd
Same problem and same resolution here. The unsion ebuild should _really_ be updated!
Is this still a problem with 2.17?
I fixed up font-schumacher-misc keywords so you can safely add it as a dep.
there is more going on here. I get the same uncaught exception Gpointer.Null, but for me it happens right after unison starts up, and regardless of gui or nogui. unison did use to work before I upgraded xorg x11. #0 0x00002b007b654cdf in poll () from /lib/tls/libc.so.6 #1 0x00002b007b33ce3c in g_main_context_acquire () from /usr/lib/libglib-2.0.so.0 #2 0x00002b007b33d20a in g_main_loop_run () from /usr/lib/libglib-2.0.so.0 #3 0x00002b007a3a54a5 in gtk_dialog_run () from /usr/lib/libgtk-x11-2.0.so.0 #4 0x0000000000533156 in ml_gtk_dialog_run () #5 0x000000000054eebc in caml_c_call () #6 0x00002b007ca1e2a8 in ??

let me add some more info: [1] I was wrong: this is a pure gui bug. (I earlier thought it was in both modes, because when given a filename of a synch file, I thought it would do text mode. It does not.) [2] this bug persists through unison 2.19.27, which is their most recent version. (PS: maybe this should go into the gentoo tree, too. 2.17.1 seems a bit dated.) [3] as noted, if someone knows how to pinpoint the ocaml line that throws this exception, I would love to find out. then again, maybe it is a gtk bug. I confirmed that gaim works on my system, so it is not that gtk+ is entirely broken. [4] any suggestions what other packages I might emerge (or upgrade to unstable on amd64) that could solve this? sincerely, /ivo welch
Okay, i added the font-schumacher dependency for modular-x users in the latest beta and stable ebuilds. I did not find the 2.19.27 version on the site so I couldn't add it though. Sorry for the long delay. Leaving as assigned as the fix is not quite that robust, say it if it works for you or not.
the schumacher font may work for some people, but not for all. on my system, it is not sufficient. to experiment, I grabbed the latest source 2.19.27 from the unison website. then I went to the newest gentoo version of ocaml 3.09.2. I also recompiled lablgtk with it. the unison source no longer compiles now: ocamlopt -I lwt -I ubase -I +lablgtk2 -c /tmp/unison-2.19.27/src/uigtk2.ml File "/tmp/unison-2.19.27/src/uigtk2.ml", line 1431, characters 10-17: Warning Y: unused variable current.

No ivo, the only important error is the last one: "/usr/lib64/ocaml/lablgtk2/gdk.cmx is not a compilation unit description". You certainly have a problem with your installation of lablgtk.
A restart of xorg is not required: just type "xset fp rehash" after media-font/font-schumacher-misc is merged.
