Hello, I've recently upgraded Gwenview to 5.0.0pre in Archlinux and found some issues with thumbnails after the upgrade, however I solved them thanks to the help of the KDE and Arch communities!

However now gwenview is crashing when entering a folder with big xcf, png and tga files (some +15000px wide or +1.5GB). It used to work before the upgrade. It seems to be working ok with smaller files.
Also, it's not saving thumbnails after quiting, it has to recreate them each time its restarted, is that normal? I assume not since it has the option to delete or not the thumbs. This was already happening before the upgrade.

Anyways, here are some logs:

Code: Select all

Until here it seems to be working ok, it shows the thumbs despite the messages.

This are the logs of the big files folder:

[Crashing directory logs end]

Again, despite the "Could not generate thumbnail for file" message the thumbs works for those named files, the crashing seems to happen with other files (there are some tga files also).
I'm monitoring free memory since gwenview uses more than 5gb during the thumbnail creation, but even though the RAM seems to fill up, the swap is not getting used even to 20% of it's size at the time of crashing.
any hints??
thanks in advance!!

I add a crash report:
