Bugzilla Bug 85153

When i try to run gnome-font-viewer i get this error:

$ gnome-font-viewer arial.ttf
Segmentation fault

I've tried emerging control-center without CFLAGS and CXXFLAGS but i still get a segmentation fault.

Me too.

Created an attachment (id=55607) [details]
patch to xorg-x11-6.8.2-r1.ebuild to apply the previous patch

This bug seemed similar to http://bugzilla.gnome.org/show_bug.cgi?id=158551
(also a gnome-font-viewer crash although the way to trigger it seemed
different), which was really https://bugs.freedesktop.org/show_bug.cgi?id=1951
(a bug in libXft). So I massaged that patch a bit to apply to xorg-x11's
internal Xft lib, and this made the crash go away for me.

The patch itself is probably good, the way I'm making the ebuild apply it
sucks. Tt would be nice to see if this fixes it for other people too.

I'm not sure this is the currect place but I think that now this bug will be
cc'ed to xorg-x11 mantainer... libxft is now provided by xorg-x11, but there is
a separated source tree
(http://lists.freedesktop.org/archives/xorg/2005-March/007192.html) and,
judging from what keith packard wrote in the bug Marien linked, it should be
better than the xorg monolithic version. is there a reason for using the one in
xorg?

Thanks Marien Zwart, that patch worked for me to.

This looks like purely an xorg bug, then. I'll add this patch to
xorg-x11-6.8.2-r2.

Giacomo, if you're interested in splitting libXft out from xorg-x11, feel free
to supply a new ebuild and patches to xorg-x11 to do so in a new bug.
Modularization work similar to this is underway upstream and should be done in
the next ~6 months, so my motivation for replicating it isn't very high.

Fixed in 6.8.2-r2 and 6.8.99.5. Thanks!
