Okular always crashes

[teracow]

Hi all,

Since moving up to Trusty (14.04 Desktop 64b), I've not been able to use Okular even once. It crashes immediately when clicking on a pdf to load (via nemo). I can open Okular manually, but it then crashes when I attempt to load a pdf via file -> open.

Here's a terminal session. This is a straight open and close of Okular with no problem (but without loading a document):

$ okular
Bus::open: Can not get ibus-daemon's address. 
IBusInputContext::createInputContext: no connection to ibus-daemon 
$

After loading Okular, I clicked on a file in "open recent":

$ okular
Bus::open: Can not get ibus-daemon's address. 
IBusInputContext::createInputContext: no connection to ibus-daemon 
Xlib:  extension "RANDR" missing on display ":0".
Xlib:  extension "RANDR" missing on display ":0".
Can't get XRandR version 
okular: Fatal IO error: client killed
$

Here's one where I clicked on open then selected a pdf that had not been loaded before:

$ okular
Bus::open: Can not get ibus-daemon's address. 
IBusInputContext::createInputContext: no connection to ibus-daemon 
Object::connect: No such signal org::freedesktop::UPower::DeviceAdded(QDBusObjectPath)
Object::connect: No such signal org::freedesktop::UPower::DeviceRemoved(QDBusObjectPath)
Xlib:  extension "RANDR" missing on display ":0".
Xlib:  extension "RANDR" missing on display ":0".

okular: Fatal IO error: client killed

This one was was also followd by a KDE Crash Handler dialog with this shown on the Developer information tab:

Versions:
according to Muon I have the following:
Okular - version 4:4.13.0-0ubuntu1
libpoppler44 - version 0.24.5-2ubuntu4
poppler-utils - version 0.24.5-2ubuntu4

Can someone please advise me further?

Thanks.

Verify that ibus is still installed.

Hi Snowhog,

No, ibus wasn't installed. So I installed it:

$ sudo apt-get install ibus

This has now removed the ibus related errors but the original problem remains:

$ okular

Maybe connected - a KDE bug report: https://bugs.kde.org/show_bug.cgi?id=333639

Are you using the Xinerama ?
Is the XRandR disabled ?

Hi Rog132,

Right on both counts!

Hmmm... looks like the use of my 2 x Nvidia cards is a bigger problem than I thought. I run multiple GPUs and I've also got an issue with KDED (as mentioned here) - same as the bug reporter in the link you provided.

So... what should I do now?

Use another pdf reader, at least till the bug is fixed?
