Description Dario Massarin 2009-09-24 12:33:49 UTC

Application: konqueror (4.3.68 (KDE 4.3.68 (KDE 4.4 >= 20090916)))
KDE Version: 4.3.68 (KDE 4.3.68 (KDE 4.4 >= 20090916)) (Compiled from sources)
Qt Version: 4.5.1
Operating System: Linux 2.6.29-gentoo-r5 i686

What I was doing when the application crashed:
Nothing particular to declare. Konqueror was opened with some tabs. When I tried to close the last one, it crashed.

SVN commit 1028058 by dfaure:

Better fix for 208374 (close tab with findbar shown)
which also fixes 194850 (close tab while it's loading, triggers setFocusNode somehow) :

make sure that no setFocus() from the dtor will trigger a part manager that knows
about this part, by unregistering the part from the partmanager(s).
