[okular] [Bug 372161] okular crash on startup

--- Comment #8 from Christoph Feck  ---
If you are still having this issue, I suggest to run okular via 'strace' to
check which Qt5 library it tries to load. It could be a VLC plugin, a
kdeconnect plugin, or something else.

In either case, it is a distribution setup problem. A Qt4 application should
never load a Qt5 plugin, because the paths must be different.

It cannot be nouveau specific as I use radeon driver.

After spending way too much time on this, I came to a partial resolution.
The problem seems to be related to EGL. The crash goes away by I disabling
EGL support in Qt 4. I am running Mesa, Nouveau and GL3 Plasma backend.
I suspect the issue arises somewhere in Mesa/Nouveau.

This must be rolling release specific (thus specific with slots). I have
removed all qt4 libraries and all dependent packages, then reinstalled okular
(again with dependencies) and the bug gone.

I am experiencing exactly the same issue on a Gentoo box.

okular -v
Qt: 4.8.7
KDE Development Platform: 4.14.26
Okular: 0.26.1

I do have both Qt5 and Qt4 present ... however there was no issue until a
recent update a few days ago. I attach an strace log. Some qt5 shared libs are
loaded ... but I have no idea what is ok or not.

It looks like you are mixing Qt4 and Qt5 packages. Unfortunately ArchLinux does
not provide debug packages, so your only option is to run it through "strace"
to see which libraries Okular tries to load.
