[Python-modules-team] Bug#727555: python-qt4: Crashes plasma-desktop on startup

Thu Oct 24 09:05:05 UTC 2013

Hi again,

some more information:

* Just upgrading python-sip (and leaving python-qt4 at the old version)
also triggers the crash.

* Uninstalling veromix fixes the crash.

* I attached the backtrace.

Kind regards
Ralf
