Since my last emerge sync, gtk applications segfault when ran as user. Root can run them; xchat works when setuid. Examples: $gdb gimp: (...)

Woops... file system error, something wrong on ~/.gtkrc-2.0. Removing it bought everything up again.
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.
assigning to gtk-engines-qt maintainers
please provide a backtrace (type 'bt' in the gdb shell) for the apps that segfault
Get back to us with something more useful. http://www.gentoo.org/proj/en/qa/backtraces.xml
