[Linux] Sudden error on startup

[iomari]

Greetings,
My current configuration is opensuse 13.2/plasma 5.

I have been using Calibre for many years always keeping the latest version.
Usually I just download the latest tarball, uncompress it and place it in my opt folder then I run postinstall and all is well.

I recently was not happy with the fact that the app did not share the same theme as my current plasma 5 desktop . I noticed that even when I select "system default" in "look and fell" it still does not work. Then I found a opensuse repo with the latest version of calibre 2.48 so I installed it and the theme was a perfect dark theme like the rest of my OS.

Then a few days later I got greedy and wanted to also install from source to a different directory but after spending a whole day trying to get it to work I gave up.

But now when I load the version from the opensuse repo I get:

calibre, version 2.48.0
ERROR: Startup error: There was an error during calibre startup. Parts of calibre may not function. Click Show details to learn more.

Traceback (most recent call last):

config['cover_flow_queue_length']+1)
TypeError: PictureFlow(): argument 1 has unexpected type 'Main'

I have uninstalled and reinstalled it several times but I still get the same error.
If I run the version from the opt folder that I originally installed, it still works although there's no dark theme.

So what can I do to get back the version from the opensuse repo that was happily working before I started compiling the source?

BTW, I completely uninstalled the source long ago so I don't think that's the problem.

thanks in advance

I believe that error is because you need to recompile calibre's binary plugins against the latest version of PyQt.
When that (PyQt) update hit ArchLinux, I had to run `python2 setup.py build --clean && python2 setup.py build`

If this is your distro package, file a bug report -- they should have rebuilt their calibre package after they upgraded PyQt 5.4 ==> 5.5

Thanks,
I'll look into that.
