After recent upgrade I have discovered that gutenprint gimp plug-in is not working anymore. It try to print, and then freezes. Investigating the situation I understand that after a page processing gutenprint receive SIGUSR1, but it is blocked. This is because gdm bug discussed at https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=756068 and fixed at https://bugzilla.gnome.org/show_bug.cgi?id=731228 Applying the patch https://bug731228.bugzilla-attachments.gnome.org/attachme really fixes the problem with gutenprint. Reproducible: Always
