Bug 310256

Application: dolphin (2.0)
KDE Platform Version: 4.8.3 (4.8.3)
Qt Version: 4.8.2
Operating System: Linux 3.2.0-2-amd64 x86_64
Distribution: Debian GNU/Linux testing (wheezy)

-- Information about the crash:
- What I was doing when the application crashed:
I had multiple tabs open for multiple directories, on various hard drives and USB devices.  I had just copied many GBs from a USB drive to an internal drive, ejected the USB drive, filtered one of my tabs, and Dolphin crashed.

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