Bug 345576

Application: dolphin (4.14.2)
KDE Platform Version: 4.14.2
Qt Version: 4.8.6
Operating System: Linux 3.13.0-37-generic x86_64
Distribution: Linux Mint 17.1 Rebecca

-- Information about the crash:
- What I was doing when the application crashed: had 3 other programs running when crash occurred 1. K3b was in the process of formatting a 4.3GB DVD/RW 2. Firefox was running with only one tab open 3. Thunderbird was in the process of downloading new emails from 6 accounts

Had plugged in external harddrive while Dolphin was running, cut 7 files (3.2gb total) to paste to external drive, clicked on external drive when crash occurred.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Dolphin (dolphin), signal: Segmentation fault
