Bug 237482

Application: dolphin (1.4)
KDE Platform Version: 4.4.2 (KDE 4.4.2)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-22-generic-pae i686
Distribution: Ubuntu 10.04 LTS

-- Information about the crash:
Shift selecting multiple files in Dolphin, not many (approx 20) seems to cause issues, looks like this has already been reported a few times (see possible duplicates). My coding knowledge is a bit rusty but it seems related to multiple threads requesting memory.

The crash can be reproduced some of the time.

 -- Backtrace:
Application: Dolphin (dolphin), signal: Aborted
[Current thread is 1 (Thread 0xb5175710 (LWP 19912))]
