Description OsamaK 2011-06-02 11:37:50 UTC

Application: okular (0.12.2)
KDE Platform Version: 4.6.3 (4.6.3)
Qt Version: 4.7.2
Operating System: Linux 2.6.35.13-libre.91.fc14.i686 i686
Distribution (Platform): Fedora RPMs

-- Information about the crash:
- What I was doing when the application crashed:
It seems that the Okular program comes with the kdegraphics in Fedora, but at least on Fedora 14 Okular crashes on startup after displaying the error message "Unable to find the Okular component."
I'm not sure if this is a Fedora bug (please let me know if it is), but Okular shouldn't crash anyway and only the error message should be displayed.

The crash can be reproduced every time.

The fact that crashes when the component can not be found is a bug and i just fixed it. The fact that the component could not be found is a problem in fedora packaging and you should complain to them.

Thanks for reporting the issue.

okular (0.12.2) on KDE Platform 4.6.2 (4.6.2) using Qt 4.7.2

I'm running Ubuntu 11.04, and Okular crashes everytime I try to open it. It worked when I first downloaded it, but after restarting my computer one time, it stopped working, with the error message "Unable to find Okular component."

Comment 3 Davor Cubranic 2011-08-25 14:38:42 UTC

Charles, I run Okular on Kubuntu 11.04 and never saw this problem. (Are you on Ubuntu or Kubuntu, BTW? Gnome or KDE?) 

Did you install it from the package manager or by hand?

Read the comment preceding yours: the fact that an Okular  component is missing is your distribution's problem, there is nothing Okular devs can do. File a bug at launchpad.net about this to let (K)ubuntu guys know. You can also try uninstalling Okular and installing it again.

Comment 4 clcharlam 2011-08-26 00:58:42 UTC

I'm running Ubuntu 11.04 with Gnome. I installed it from Synaptic, and I realized that it requires at least kdegraphics to run, so I installed that too. But uninstalled both (okular and kdegraphics) and reinstalled a couple times, but to no avail.

Comment 5 Davor Cubranic 2011-08-26 15:43:10 UTC

Charles, you should definitely file your issue with Ubuntu on Launchpad, I don't think there are any Ubuntu devs here to help you.

And you didn't need to add OsamaK to this bug's CC list, he would already get emails as the reporter.
