Application: dolphin (1.4)
KDE Platform Version: 4.4.00 (KDE 4.4.0) (Compiled from sources)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-gentoo-r6 x86_64
Distribution (Platform): Gentoo Packages

-- Information about the crash:
KDE was compiled from svn on amd64 gentoo, using CFLAGS="-O1 -march=core2 -mtune=core2 -pipe -ggdb"

I was deleting 4 700MB files using Del (key) which sits on another hard drive, mounted as /storage.
After I was noticing that Dolphin was moving the files to the trash:/ folder on the first hard drive I clicked cancel on the operation and Dolphin crashed.

It might be noteworthy that both hard drives are encrypted.

The crash does not seem to be reproducible.

 -- Backtrace:
Application: Dolphin (dolphin), signal: Segmentation fault
The current source language is "auto; currently c".
