[solved] Okular: Icon theme "crystalsvg" not found.

Hi, I updated my machine two or three weeks ago and found that Okular no longer works.

Icon theme "crystalsvg" not found.
Icon theme "crystalsvg" not found.
Segmentation fault (core dumped)

I tried to find the "CrystalSVG" pacage but those do not seam to be in the repo.
Any sugiestions on how to fix this?

Re: [solved] Okular: Icon theme "crystalsvg" not found.

Crystal SVG was the default icon theme for kDE 3.1, it may have been removed with a recent update.

Check KDE theme settings.

Disliking systemd intensely, but not satisfied with alternatives so focusing on taming systemd.

clean chroot building not flexible enough ?
Try clean chroot manager by graysky

I really doubt those missing icon messages have anything to do with the segfault. Please post a backtrace.

Re: [solved] Okular: Icon theme "crystalsvg" not found.

A changing KDE theame could be a way to solve this.
I do not use KDE as DE so how do I change it?

GDB gave me this:

Re: [solved] Okular: Icon theme "crystalsvg" not found.

Perhaps the icon theme is the problem.
In this Wiki they say that QT5 is using the installed DE to determine the ICON package.
But as I use Awesome WM it does not provide those systems.
Thus I installed the qt5ct package and started the application without setting the eviromental variable QT_QPA_PLATFORMTHEME.
Thu the qt4ct started with an error, locking ugly.

$ export QT_QPA_PLATFORMTHEME=qt5ct
$ qt4ct

And restart the qt5ct resulted in a working qt5ct.

But then I started Okular again and got:

So it seams to be that I need to install a new iconteam for QT5.

You are using an unsupported style. It's your task to rebuild it every time Qt gets updated.

Re: [solved] Okular: Icon theme "crystalsvg" not found.

r00tr4t, use pacman -Qo /usr/lib/qt/plugins/styles/libbb10styleplugin.so to find out which package owns that file.

I expect it will be the aur qt5-styleplugins package .

I understand. I forgot to update the aur pacage. I'm doing it right now and will report back to see if the problem is solved.

Yes as @Lone_Wolf and @arojas mentioned the qt5-styleplugins needed to be updated.
