[Pkg-utopia-maintainers] Bug#561088: A part of dbus segfaults locking X11, unblock trough "dbus restart"

[JP Pozzi]

Package: dbus
Version: 1.2.16-2
Severity: important

Hello,

Since some days I encounter a problem implying a restart of dbus.
The X system locks (likely on file operations) and can only be unlocked by restarting the dbus service.
DMESG lists many segfaults :

When I launch a GNOME session i have to restart dbus to get the panels and at least another time to get Nautilus working.

Some operations (mainly implying file operations) stay locked until I restart dbus. Listfile panel becomes grey with nofiles, after restarting dbus the list of files is OK.

Regards
