Bug 297112

Application: konqueror (4.7.4 (4.7.4))
KDE Platform Version: 4.7.4 (4.7.4)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-17-generic-pae i686
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed:

I was using Konqui in FileManagement mode to tidy up my home directory by moving things into folders or deleting them.  In the one konqui instance, one tab, I had three panes open:

1: viewing home directory, locked to current directory, view linked to pane 3
2: viewing other directory, not locked, not linked
3: viewing file contents, not locked, but linked to pane 1
(the use case obviously being that I could click on a file in pane 1, preview its contents in pane 3, and then either delete it or drag it to the appropriate folder in pane 2).

I had noticed that this konqui instance was getting quite slow to respond - it was newly opened for this purpose so didn't have any old URL history hanging around.  This counts as unusual behaviouor as Konqui is normally pretty quick to respond in the file management view.

In order to delete an oddly named directory I had opened the Terminal Emulator view, done the rm and then closed the view, shortly before the crash.  I don't know if it was related.

I then clicked on a few more files and dragged them across.  After a few seconds further moving files around, konqui crashed.  Can't tell whether it was in response to the previous click-and-drag or to the next click as they were quite close together.
