Sentry Crash Report:

Description Axel Krebs 2013-07-21 18:18:52 UTC 
Application: konqueror (4.10.5)
KDE Platform Version: 4.10.5
Qt Version: 4.8.4
Operating System: Linux 3.8.0-27-generic x86_64
Distribution: Ubuntu 13.04

-- Information about the crash:
- What I was doing when the application crashed:

For file and directory purposes, I often use two (or three) windows within _one_ konquerer instance.

If closing one subdirectory (window), the program empties all or crashes.

The crash can be reproduced every time.

-- Backtrace:
Application: Konqueror (kdeinit4), signal: Segmentation fault

This is using konqueer with two windows-- left and right. 
I use this arrangement to drag-and.drop files from one directory to the other one.
Hope I could clarify.
Sorry for delay
