Bug 294641

Application: kgpg (2.7.0)
KDE Platform Version: 4.8.00 (4.8.0 (Compiled from sources)
Qt Version: 4.8.0
Operating System: Linux 3.2.7 i686
Distribution (Platform): Gentoo Packages

-- Information about the crash:
I created a sigend message :
$>echo "Hi " | gpg --verbose --sign --recipient mickey@mou.se --armor --output signed.txt.asc
opened it in Dolphin (sigend.txt files was created) and opened it twice-. A dialog poped up to overwrite the file and then (or few seconds before ?) the crash occured.

-- Backtrace:
Application: KGpg (kgpg), signal: Segmentation fault
