Bug 315976

Application: plasma-desktop (0.4)
KDE Platform Version: 4.9.4
Qt Version: 4.8.3
Operating System: Linux 3.5.0-22-generic x86_64
Distribution: Ubuntu 12.10

-- Information about the crash:
In Dolphin, I highlighted a ~35 MB file from my home directory, pressed control-C to copy it, opened a new tab in Dolphin with ctrl-T, selected from the left-hand "Devices" list an NFS-mounted drive.  The directory of that drive appeared, then I pressed ctrl-V to paste that file.  The target NFS box happens to be right next to me and I heard it spinning up a drive (presumably the target of this operation).  I noticed within a few seconds that I wasn't seeing a copy progress dialog, so clicked on Dolphin to get ready to hit refresh on the directory.  Then I noticed that Dolphin was unresponsive: I couldn't change tabs, couldn't select files, etc.  After about 30 seconds Plasma crashed and I got this error submit dialog.

-- Backtrace:
