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 3.0.0-16-generic-pae i686
Distribution: Ubuntu 11.10

-- Information about the crash:
I started konqueror on an smb://host/directory kio link.  I navigated to another directory on the same host by doing "up" and then choosing another public share.  I think Konqui was using the File Management profile as the sidebar came up automatically showing the icons available for the various tabs, although the entries in it were not expanded.   (this unexapnded view is a papercut annoyance that it often does on browsing local files too, whereas KDE3 used to remember the expanded/unexpanded state).

I wanted to add the new share to the "Network" on my sidebar so I tried to pull the sidebar wider.  It did not respond to a couple of attempts, although normally it would.  I then pressed F9 twice to hide the sidebar and re-open it again just to check that I was interpreting the display correctly.   On the second F9, konqui displayed the sidebar (still un-expanded) and then crashed.

When I repeated this, the sidebar came up as still unexpanded and would not expand by dragging out.  however on this second occasion, F9 F9 closed the sidebar and then re-opened it at the correct width.

The crash does not seem to be reproducible.
