I can confirm this problem. Krusader crashes immediately after startup. I also tried deleting krusader's settings but it did not help.

I removed ~/.kde/share/config/krusaderrc and segfaults are gone. But I think this should not happen after upgrade. Unfortunatelly I don't have backup of that krusaderrc to reproduce the problem again.

krusaderrc Edit (2.3 KiB, text/plain)

I have same problem as described in this bug report on Ubuntu 10.04 (krusader 1:2.0.0-1ubuntu3).

In my case problem was with value of "Left Active Tab" in krusaderrc at "[Startup]" section - looks like it was greater than total number of saved tabs at left panel.

Workaround for this bug is to open ~/.kde/share/config/krusaderrc, find "Left Active Tab=XXX" (or "Right Active Tab=XXX") and replace it with "Left Active Tab=0" ("Right Active Tab=0").

More stable option, I think, will be in removing whole "[Startup]" section.

Attaching configuration on which bug can be reproduced with following callstack:
