Application that crashed: ark
Version of the application: 2.13
KDE Version: 4.3.5 (KDE 4.3.5)
Qt Version: 4.5.3
Operating System: Linux 2.6.31.12-174.2.3.fc12.i686 i686

What I was doing when the application crashed:
I clicked on an archive in Dolphin, and it opened in Ark.  I dragged another archive from Dolphin to Ark, thinking it would open the second archive.  Instead, it started adding the second archive to the first.  While it was doing this, I closed Ark, and it crashed.
