Bug 118574 – GTK applications segfault

• Product: Gentoo Linux
• Status: RESOLVED NEEDINFO

[Description Pablo Barros 2006-01-10 13:10:55 UTC]

Since my last emerge sync, gtk applications segfault when ran as user. Root can run them; xchat works when setuid.

Examples:
$gdb gimp:

Re-emerged pango, gtk+, freetype2, and the applications, to no avail. Is this a severe bug, or am I missing something?

Woops... file system error, something wrong on ~/.gtkrc-2.0. Removing it bought everything up again. 

[Comment 2 Pablo Barros 2006-01-12 11:27:49 UTC]

Seems to be a bug in gtk-engines-qt. Using Plastik as KDE theme, and setting "use my KDE style in GTK applications" causes them to segfault. Reopening.

[Comment 3 Joe McCann (RETIRED) 2006-01-13 10:15:22 UTC]

assigning to gtk-engines-qt maintainers

[Comment 4 Simon Stelling (RETIRED) 2006-02-12 07:56:12 UTC]

please provide a backtrace (type 'bt' in the gdb shell) for the apps that segfault

[Comment 5 Jakub Moc (RETIRED) 2007-02-16 18:58:01 UTC]

Get back to us with something more useful.
