STEPS TO REPRODUCE
1. Open Skrooge
2. Open "Accounts"
3. Mark an item (left click with mouse is enough)
4. App crashes

OBSERVATIONS
If I start Skrooge via Konsole, I get this message (unfortunately, DrKonqui doesn't give any backtrace):

##FATAL: Cannot mix incompatible Qt library (5.15.7) with this library (5.15.8)
KCrash: crashing... crashRecursionCounter = 2
KCrash: Application Name = skrooge path = /usr/bin pid = 16158
KCrash: Arguments: /usr/bin/skrooge 

Looks like it's got somthing to do with todays qt update.
