Suddenly found possible cause/workaround for the bug. In 12.10 environment variable GTK_MODULES is set for all DE (including KDE or XFCE). If variable is unset, gdk_error_trap_pop may disappear appear when starting GTK applications.
On my desktop: $ env | grep GTK_MODULES GTK_MODULES=canberra-gtk-module:canberra-gtk-module $ fslint-gui /usr/bin/fslint-gui:1950: GtkWarning: IA__gdk_error_trap_pop: assertion `gdk_error_traps != NULL' failed gtk.main () $ unset GTK_MODULES $ fslint-gui <no GtkWarning message> Probably this bug is related to bug 385577 -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gtk+2.0 in Ubuntu. https://bugs.launchpad.net/bugs/1075928 Title: Please, silence IA__gdk_error_trap_pop: assertion `gdk_error_traps != NULL' failed To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gtk+2.0/+bug/1075928/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
