Hello,
assistant segfaults in a reproducible fashion at startup. Stack trace says:
Program received signal SIGSEGV, Segmentation fault.

I can get rid of the segfault at startup by removing
~/.local/share/data/Trolltech.
To go back to the faulty state, all I have to do is to configure the
application font to custom and click apply (with browser font it works
fine). It then segfaults and after that, it is impossible to spawn the
configuration again. Backtrace of that segfault:
Program received signal SIGSEGV, Segmentation fault.
