Package: apparmor-profiles-extra Version: 1.15 Severity: important Dear Maintainer,
Totem suffers a segmentation fault upon startup when its respective apparmor profile is set to enforce mode. It starts fine when the apparmor profile is set to complain mode. I have not modified the /etc/apparmor.d/usr.bin.totem profile. *** Reporter, please consider answering these questions, where appropriate *** * What led up to the situation? I set /usr/bin/totem to "enforce" mode and then attempted to start /usr/bin/totem from a terminal in order to display the error. I see the same behavior if I open Totem from my GNOME menu. jason@debian-testing:~$ /usr/bin/totem (totem:29696): GLib-CRITICAL **: g_strsplit: assertion 'string != NULL' failed Segmentation fault * What exactly did you do (or not do) that was effective (or ineffective)? Placing /usr/bin/totem in "complain" mode resolves the issue. * What outcome did you expect instead? I expected Totem to work properly with its apparmor profile in enforce mode.
