Overview:
Mcomix is stuck on version 2.1.0 in tumbleweed main repository. There was python pillow update to a newer version and mcomix 2.1.0 checks required versions as strings and as a result 10.0.1 is not enough for 6.0.0 required. The bug is fixed upstream in mcomix 2.3.0 but it's not in the main tumbleweed repository.

Actual results:
Application doesn't start, here's terminal output:

$ mcomix
