Can reproduce on openSUSE Tumbleweed. Does not seem to be the same issue as Bug 412986 as the symptoms are a bit different (something is printed to the console this time).

This seems to be working for me now. All apps tested launch via the button, except for Blender. I suspect that to be a packaging issue.
No error message on the terminal for blender?
Nope, nothing at all. :( What's weird is that Blender briefly shows up in the task manager with its launch feedback animation and then it disappears, but the app isn't launched.
