Bug 270062

Application: python2 (1.5)
KDE Platform Version: 4.5.1 (KDE 4.5.1)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-28-generic x86_64
Distribution: Ubuntu 10.10

-- Information about the crash:
- What I was doing when the application crashed:
/etc/init.d/dbus restart
- Unusual behavior I noticed(before the crash):
somethimes dbus seem to hang(ant hints to diag this):
- applications dont show dialogs or have unresponsive behavior
- dbus-daemon prossess uses 100% cpu
- /etc/init.d/dbus restart seems to fix it for most apps(ex.: save dialog in tsclient 0.150 pops up emidiently when dbus is restarted, while i clicked the button before)

-- Backtrace:
Application: Printer Applet (python2.6), signal: Segmentation fault
