Hi, Krita community! I very glad to return here after so long time...

But i have a problem: after a long pause in using Krita (and drawing), switched to a new OS with KDE Plasma 5.x, i unfortunately discovered that Gwenview CAN'T OPEN any .kra file. Instead it show an error mesage:
" Loading '<file_name>.kra' failed.
Loading meta information failed. "

I found the similar looking Bug 188191, except that it was about .tga and there was a thumbnail working.
But in my case, NO thumbnail show, NO image load.

By the way, i can see a thumbnails (previews) for all that .kra files in Dolphin (so, preview.png is present in an unzipped .kra).

What can i do - is it a known bug or i need to post a new one? May be a workaround? I will be very grateful for the advice.


My system:
Manjaro 17.0.1 (Arch-based),
KDE Plasma 5.9.5, Frameworks 5.34.0
Gwenview 17.04.1-2

PS: When i run a Gwenview from console and open in it a folder with .kra files, there are an errors:

QImageReader::read() using format hint "kra" failed: "Unknown error"
QImageReader::read() without format hint failed: "Unsupported image format"
Could not generate thumbnail for file "file:///<path_to_file1>.kra"
Could not generate thumbnail for file "file:///<path_to_file2>.kra"
....

Hm... It really should work if the kimageformats framework is present. I added support for kra and ora to that in in 2016.

I have:
kimageformats 5.34.0-1 (kf5)

...and all dependencies (as i can see)..

That should be new enough... I haven't got a linux system at the moment that is up to date enough to check, my laptop failed and my desktop has a weird set of things installed. But it should've worked.

May be, this [somehow] connects with this old KDE4 bug?

(For me, it works properly only on Kubuntu 12.04 LTS)

I'm also using Manjaro KDE and I have exactly the same problem. I don't think any bugs in the bug tracker describes this problem. Should I file a bug for this?

I suspect this is a Gwenview issue. I am on KDE neon and have kimageformats installed, and dolphin is showing kra files just fine, but have the same issue with gwenview.
