- Are your python-qt , python-kde (kdebindings) packages updated ?
The crash seems to be caused by a version mismatch between Python/Python-Qt/Qt as you probably have some python widget in your desktop.

Thanks

Comment 2 belion 2009-11-16 13:56:24 UTC

I am upgraded to the last versions in Debian/testing

$ plasma-desktop -v
Qt: 4.5.3
KDE: 4.3.2 (KDE 4.3.2)
Plasma Workspace: 0.3

ii  python-qt4                           4.6-1                      Python bindings for Qt4
ii  python-qt4-dbus                      4.6-1                      DBus Support for PyQt4
ii  python-qt4-gl                        4.6-1                      Python bindings for Qt4's OpenGL module
ii  python-kde4                          4:4.2.2-3                  Python bindings for the KDE 4 libraries

Is the problem python-kde4 (version 4.2.2) versus KDE (version 4.3.2) ?

Comment 3 Dario Andres 2009-11-16 14:03:56 UTC

It seems that the python-qt package was updated recently and that broke "python-kde" (which was not recompiled....).
Tracking this bug at bug 214789 Thanks
