Bug#496990: gnome-panel: Gnome panel crashes with scummvm installed

[Rodrigo Chandia]

Package: gnome-panel
Version: 2.20.3-5
Severity: normal


gnome-panel crashes and sometimes hangs when clicking Applications > Games

To reproduce: install scummvm, click said menu.

Installing and removing scummvm reliably produces and removes the behavior.

Doing a

$strace gnome-panel --sync

gives:

Interestingly,

$ strace -o panel-trace gnome-panel --sync

Does not give the same error. It hangs and gives a double free error instead of a segfault.
