Package: kdiff3
Version: 1.10.0-1
Severity: important

I tried to compare 2 directories with kdiff3 and it crashed the moment
it was supposed to show the diff.
This happened initially when selecting the dirs in Dolphin.
Then via the crash handler I restarted kdiff3 and was presented with a
dialog to select files/folders to compare. Selected the same 2
directories again and it crashed immediately.

The KDE Crash Handler said the trace was useful, so copied below:

Application: KDiff3 (kdiff3), signal: Aborted
