Bug 280414

Application: yakuake (2.9.6)
KDE Platform Version: 4.5.3 (KDE 4.5.3)
Qt Version: 4.7.0
Operating System: Linux 2.6.32-33-generic x86_64
Distribution: Ubuntu 10.04.3 LTS

-- Information about the crash:
- What I was doing when the application crashed:
Closing tabs in yakuake using ctrl+D

This does not always happen, but quite often. It notably does not seem to happen when closing the first tab directly after starting yakuake (i.e. without ever opening a new tab).

- Unusual behavior I noticed:
My home directory is on a server on the network and connected via NFS (I think, haven't really checked in detail since I'm no full admin here).
I had some problems with dbus and qdbus which caused sound not to work once. autofs restart was needed to fix it.
Amarok also previously took a long time to load until I upgraded it and when run from terminal gave lots of dbus/qdbus errors if I remember correctly.

After upgrading to KDE 4.5 via backports, I got an error message when I first started amarok and when I tried to open any file dialog from it. After reboot, everything was fine however and amarok starts faster than before.

Note that I am under a Gnome desktop in Ubuntu 10.04.3 LTS.

The crash can be reproduced some of the time.
