Hi Matthias, Are you sure about your notify-sharp (libnotify0.4-cil) version? According to [1], notify-sharp is currently only at 0.4.0~r3032-1.
Looking at that backtrace, the crash probably originated from notify-sharp. If you're sure about libnotify0.4-cil's version, then please install Debian's libnotify0.4-cil and try again. Also, please try installing notification-daemon in place of xfce4-notifyd and testing. [1] http://packages.qa.debian.org/notify-sharp -- Regards, Chow Loong Jin
