Bug 279789

Application: krusader (2.2.0-beta1 "DeKade")
KDE Platform Version: 4.4.5 (KDE 4.4.5)
Qt Version: 4.6.3
Operating System: Linux 2.6.32-5-amd64 x86_64
Distribution: Debian GNU/Linux 6.0.2 (squeeze)

-- Information about the crash:
Started Krusader, closed the last tab on the left pane, then closed the first tab on the right pane and crash occured. The same situation when closing these two tabs in reverse order (the first right closed fine, closing the last left caused segmentation fault). Note, that many tabs were open on both panes (12 on left and 11 on right).

The crash can be reproduced some of the time.

 -- Backtrace:
Application: Krusader (krusader), signal: Segmentation fault
The current source language is "auto; currently asm".
