Description Andrey Borzenkov 2009-11-09 18:40:20 UTC
Application: konqueror (4.3.73 (KDE 4.3.73 (KDE 4.4 >= 20091026)))
KDE Version: 4.3.73 (KDE 4.3.73 (KDE 4.4 >= 20091026))
Qt Version: 4.6.0
Operating System: Linux x86_64
Distribution: "Mandriva Linux 2010.0"

What I was doing when the application crashed:

Konqueror crashed closing one tab while browsing Vmware site. Stack crash looks similar to 212213 but is slightly different.

Comment 1 Frank Reininghaus 2009-11-09 19:48:04 UTC
Thanks for the bug report! This looks indeed similar to bug 207173, but it looks like you had an Okular part open in the closed tab. Maybe the root cause is similar to the issue fixed by David in the KHTML part.

I'll CC the okular-devel mailing list.

Comment 4 David Faure 2009-11-13 16:28:12 UTC
Hmm, I should fix this at the konqueror level then, so that focus changes inside a part that is being deleted, are not taken into account.

Created attachment 39522 [details]
similar crash backtrace

another similar backtrace, would be nice to have this bug fixed
(backtrace with kde-4.3.3, I accidentally deleted the backtarce with 4.3.4 but it looks the same)
Hope this backtrace helps a bit :)
Comment 8 Dario Andres 2010-01-07 12:53:07 UTC
From bug 221625:
-- Information about the crash:
I closed one instance of konqueror with 2 tabs opened. In one of them I was
viewing a pdf using okular, in the other one I viewed a website.

Comment 11 David Faure 2010-03-16 20:55:32 UTC
First step: reproducing the bug. Using the pdf from bug 214380 I found the following steps:
* konqueror http://www.oedp.de/files/pdf/programme/BundespolitischesProgramm.pdf
* Ctrl+T (to get a second tab)
* Back to first tab, click on an entry in the table of contents (important so that it has focus).
* Ctrl+W (close tab) -> crash.

Okular::Document::closeDocument calls TOC::hasTOC(false), which hides the TOC widget, which triggers a focus change (the Sidebar gets focus), which PartManager notices, and it tries to set the okular part as active again.

OK, removing part from PartManager before deleting it, seems to work. Commit coming up.
Comment 12 David Faure 2010-03-16 21:02:49 UTC
SVN commit 1104129 by dfaure:

Move up the fix for 207173 (crash when closing khtml tab with focus in findbar) from khtml to konqueror,
so that it also fixes 213876 (crash when closing okularpart tab with focus in sidebar) :
unregister part from partmanager before deleting it.
