4th crash and we start to see a pattern here.
The 3rd and 4th crashes are almost identical.
Only similarity between all 4 so far is the incidence of qrichtext.cpp
Coincidence ?

If it helps, the following fonts are set:
Chat text: Sans Serif 12
Nickname list: Sans Serif 10
Tab bar: Sans Serif 10
Fixed font for MOTD messages is enabled.

Backtrace follows:

Using host libthread_db library "/lib/libthread_db.so.1".
