Subject: python-qt4: Python plasmoids causes plasma-desktop to crash -> KDE is unusable

Package: python-qt4
Version: 4.9.1-3
Severity: important

Dear Maintainer,
Today's python-qt4 package update rendered my KDE desktop completely
unusable. plasma-desktop crashes on startup due to plasmoid written in
python.

I am attaching dr Konqi crash report.
I also attach tar-gzipped plasmoid that triggers the segfault. This is
badly written python code that invokes external shell script every second 
and displays it's output. I know nothing about python programming, but
this plasmoid serves me quite well. 
(for those unfamiliar with KDE:
1. untar attached file
2. run 'plasmapkg -i uptime'
3. try to add "Uptime" plasmoid)

To ensure that problem is not caused by poor quality of plasmoid code, I
also tested on another python plasmoid on fresh configuration (new
user). The problem is reproducible. Another plasmoid I have tested is:
http://code.google.com/p/gmail-plasmoid/

I have downgraded python-qt4 and python-qt4-dbus packages to 4.9.1-1 and
problem ceased to exists; both plasmoids are running just fine.

This may or may not be related to bug 672108 - I am unable to tell.

Best regards
Mirosław Zalewski
