Summary: Okular hangs and crashes (and kded4 consume 50% CPU)
Product: okular
Version: 0.12.2
Platform: Ubuntu Packages
OS/Version: Linux
Status: UNCONFIRMED
Severity: crash
Priority: NOR
Component: general
AssignedTo: okular-devel at kde.org
ReportedBy: sorokin at rain.ifmo.ru
Application: okular (0.12.2)
KDE Platform Version: 4.6.2 (4.6.2)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-8-generic x86_64
Distribution: Ubuntu 11.04
-- Information about the crash:
- What I was doing when the application crashed:
I opened pdf file downloaded from
https://github.com/boostcon/2011_presentations/blob/master/mon/leesa_boostcon.pdf
I pressed Ctrl+Shift+P (go to fullscreen)
Okular hung.
I went to other virtual terminal and killed it.
I opened this pdf file again.
I pressed Ctrl+Shift+P (go to fullscreen)
Okular hung.
I went to other virtual terminal and killed it.
...
When I returned from killing okular third time I saw this crash.
I noticed that kded4 were consuming 50% CPU (one core).
I killed kded4 and ran it again.
I was unable to reproduce this bug after kded4 restart.
- Unusual behavior I noticed:
I noticed that kded4 were consuming 50% CPU (one core).
I made a couple gdb backtraces of kded4 (I hope they are useful):
