I'm not sure but looks like same issue saber-notes/saber#1124

Could it be an issue where the program is unable to find any suitable icon/iconpack?
It failed when trying to load an SVG:

If you know how to fix this issue, you're more than welcome to help out.
Here are the AppRuns used by pelfCreator: https://github.com/xplshn/pelf/tree/pelf-ng/assets

This is the one pelfCreator uses by default: https://github.com/xplshn/pelf/blob/pelf-ng/assets/AppRun.sharun.ovfsProto

And that's the one the onlyOffice recipe is using. I don't know any of the GTK env variables wizardry that other deploy tools use, I could look into this, but right now I'm working on something else at the moment. Thanks for the bug report btw.
