The combination of glib-networking 2.28.7 and evolution-data-server-2.32.2-r1 causes a reproduceable crash when trying to access web calendars via ssl. A backtrace from /usr/libexec/e-calendar-factory tells me: (e-calendar-factory:12508): GLib-WARNING **: GError set over the top of a previous GError or uninitialized memory. This indicates a bug in someone's code. You must ensure an error is NULL before it's set. The overwriting error message was: Error receiving data: Resource temporarily unavailable Program received signal SIGSEGV, Segmentation fault. 0x00007fffe807f40d in ??

Let me know if you need more info, I can easily reproduce this.
Try with gnome-extra/evolution-data-server-2.32.3-r1 and mail-client/evolution-2.32.3 If still valid try to get a better backtrace -> http://www.gentoo.org/proj/en/qa/backtraces.xml
(In reply to comment #1) > Try with gnome-extra/evolution-data-server-2.32.3-r1 and > mail-client/evolution-2.32.3 This makes no difference, still crashes. I'll see if I can get a better backtrace.

(In reply to comment #3) [...] > #6 0x00007ffff6ee14a6 in ?? () from /usr/lib64/libgio-2.0.so.0 [...] Looks like you should also rebuild dev-libs/glib-2.28.8 with debugging symbols and, even, also install bug-buddy to let it take the crash, report to upstream and, once the upstream bug is opened, look easily for possible duplicates with similar traces (thanks to gnome bugzilla!)... if you don't know how to do that, simply post the link to upstream report here and I will check it for you ;) Thanks again
(In reply to comment #0) [...] > I'd try downgrading glib-networking but those versions are no longer available. [...] Maybe this is caused by libsoup update instead... but if you still suspect about glib-networking, I think you could simply copy existing ebuild for 2.28.6 also to test (I dropped all older versions to try to ensure all people suffering that kde/glib-networking problems were running the latest versions)
(In reply to comment #5) > Maybe this is caused by libsoup update instead... This is the correct answer. I've downgraded to libsoup{-gnome}-2.32.2 and now things work again.
Try to get a better backtrace with glib debugging symbols anyway, also try different libsoup-2.34.x versions to test Thanks
I think this could be related with bug 383851
(In reply to comment #8) > I think this could be related with bug 383851 Yes, sounds plausible given that I'm trying to connect to an SSL-hosted webdav. It seems that Apache doesn't allow configurable ephemeral Diffie-Helman sizes (which seems to be what this is about), so I can't test it by setting this to a larger value.
Please re-test with that updated versions that are available in the tree for some time
