Sentry Crash Report:

Description David Palacio 2009-09-12 13:47:27 UTC 
Application: konqueror (4.3.68 (KDE 4.3.68 (KDE 4.4 >= 20090907)))
KDE Version: 4.3.68 (KDE 4.3.68 (KDE 4.4 >= 20090907)) (Compiled from sources)
Qt Version: 4.5.1
Operating System: Linux 2.6.26-2-amd64 x86_64
Distribution: Debian GNU/Linux 5.0.3 (lenny)

What I was doing when the application crashed:
Konqueror crashes on some tab close. It is random, not reproducible with the same conditions.
Backtrace looks the same for me in bug #171179 (which does not seem like a duplicate of bug #173473 to me)

 -- Backtrace:
Application: Konqueror (kdeinit4), signal: Segmentation fault

Hide the whole widget, not just the view and the viewport. Otherwise the findbar stays around,
receives focus, and this makes the partmanager activate the part that we're currently deleting...

Forgot to do this before 4.3.2, so the fix will be in 4.3.3 :(
