Application: konqueror (4.8.4 (4.8.4))
KDE Platform Version: 4.8.4 (4.8.4)
Qt Version: 4.8.2
Operating System: Linux 3.2.0-4-amd64 x86_64
Distribution: Debian GNU/Linux 7.11 (wheezy)

-- Information about the crash:
- What I've done:
Clicked on a tar archive file (90MB or so), so that the internal archive viewer should show the content and then during the system was working on that, I clicked the back button. And Konqueror crashed. Tested several times, and during the opening process, the back button will crash the complete application
- Unusual behavior I noticed:
often Konqueror does not really refresh the file list, although some things have changed (new files, new foldernames,...), but I guess this is another bug, which is known

The crash can be reproduced some of the time.

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