Bug 279408

Application: plasma-desktop (0.4)
KDE Platform Version: 4.6.5 (4.6.5)
Qt Version: 4.7.3
Operating System: Linux 2.6.39-2-amd64 x86_64
Distribution: Debian GNU/Linux testing (wheezy)

-- Information about the crash:
Running Debian Testing, KDE 4.6.5.  I closed amarok 2.4.1 from the system tray and started APT upgrading amarok to 2.4.3.  I left it running whilst I read Usenet with trn (console app).  Plasma crashed spontaneously whilst the amarok binary was being replaced.

-- Backtrace:
Application: Plasma Desktop Shell (plasma-desktop), signal: Segmentation fault
