Description Ron 2009-04-20 13:17:02 UTC 
Version:           1.2.1 (using KDE 4.2.2)
OS:                Linux
Installed from:    Ubuntu Packages

Anytime I close the dolphin window too quickly after deleting some files from that window it causes dolphin to crash.  I've received a number of different crash reports.  I've included 3 of them below.

Comment 1 Dario Andres 2009-04-26 16:18:35 UTC 
@Ron: for the new time, try to not mix different crash traces in the same report as it may difficult the developers work to try to identify the crash cause. (the politic is "one report per crash") Thanks!!

The first crash could be related to bug 187167
The second and third ones seems to be unique.

Thanks for reporting
