Application: ark (2.14)
KDE Platform Version: 4.4.2 (KDE 4.4.2)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-21-generic x86_64
Distribution: Ubuntu lucid (development branch)

-- Information about the crash:
I double-clicked a file, Ark started extracting it. As the archive was big (linux-source), i closed Ark while operation was in progress. Doing it generated segfault.

 -- Backtrace:
Application: Ark (ark), signal: Segmentation fault
