-- Information about the crash:
Dolphin is unstable when browsing an OwnCloud-synced directory. The crash seems to happen randomly, but a somewhat reliable way to trigger it is to add new files to the synced folder.

The crash can be reproduced sometimes.

Application: Dolphin (dolphin), signal: Bus error
Using host libthread_db library "/usr/lib/libthread_db.so.1".
