Hi,
Since the last qt5 update calibre crashes at startup with a Segmentation Fault.
Here's the back trace:

I'm using the pentium4 repos and my DE is KDE Plasma.

Confirmed. And its /usr/bin/python2 called by calibre, which is segfaulting. Maybe a Qt/Python binding issue..

FYI this is still happening with 3.44.0-3.0.

Also a rebuild issue around Qt and python2 (though Qt should depend actually on Python).
