Bug 313179

Application: dolphin (2.1)
KDE Platform Version: 4.9.5
Qt Version: 4.8.2
Operating System: Linux 3.2.0-36-generic x86_64
Distribution: Ubuntu 12.04.1 LTS

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

Dolphin just crashed halfway through copying a bundle of ~10 files to the external USB drive. This is not reproducible, but Dolphin crashes became more frequent (for quite random reasons) since the update to KDE 4.10.

The crash can be reproduced some of the time.

-- Backtrace:
Application: Dolphin (dolphin), signal: Aborted
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
