Description Marcel Partap 2010-07-19 15:04:54 UTC

Application: konqueror (4.4.4 (KDE 4.4.4))
KDE Platform Version: 4.4.4 (KDE 4.4.4)
Qt Version: 4.6.3
Operating System: Linux 2.6.32-5-686 i686
Distribution (Platform): Debian unstable

-- Information about the crash:
While i can't exactly pin down why the freshly restored session does crash, it points to another bug: session restore doesn't honour the setting for launching each window in its own instance. So the session gets restored as one process - a faulty flsht plugin or a khtml bug takes it all down again. Moreover, the session restore list really should be a tree of checkboxes, so individual tabs/windows can be excluded from restoration. And why does it ask on EVERY window opening? Because of mentioned behaviour, i became accustomed to pressing the 'ask me later' button (on my debian lap - have applied a patch on my gentoo box to skip that), so more and more old sessions accumulated. Accidently pressing enter after calling konqueror *with an external URL* would then bring everything to a halt while konqueror tries to restore all the old sessions - only to choke and crash on on tab. Hope one can get the idea where the points for improvements are ;)

The crash can be reproduced some of the time.

Comment 1 Dario Andres 2010-12-15 18:25:15 UTC

[Comment from a bug triager]
The crash itself seems related to the Okular/libpoppler code (PDF viewer part). I can't really tell about the other problem described
Regards

Comment 2 Albert Astals Cid 2011-01-08 14:14:26 UTC

It might seem to be crashing open a pdf file, do you have the pdf file url that caused that crash?

Comment 3 Marcel Partap 2011-11-22 14:35:57 UTC

Uuhm, sorry i overlooked the replies just saw the change to okular component and while technically it might be a crash within some poppler code, i can not give a testcase URL, and also this bug was primarily about the konqueror session restore implementation being of low scalability and robustness...

Comment 4 Albert Astals Cid 2011-11-23 22:57:20 UTC

Giving back to konqueror as per user request.

But basically you are asking for something impossible. If Okular is crashing it will bring down konqueror with it.

Comment 5 Dawit Alemayehu 2011-12-22 03:01:58 UTC

There are many things bunched together in this bug report. For your session management problems, please open a separate bug report or find one that matches your issues in the bug database and add your comment on it. There are many session management related reports against konqueror. 

This is a crash related ticket that was in Okular/libpopler and since you were unable to provide a URL to reproduce the crash, there is nothing that can be done for it.
