Because of breaking changes in python2-pillow (and python-pillow) 6.0.0, MComix 1.2.1 is currently totally broken and unusable in Testing and Unstable. When trying to launch it from the terminal, I get the following output:
[ami@xfcenew Bureau]$ mcomix Traceback (most recent call last): File "/usr/bin/mcomix", line 11, in <module> load_entry_point('mcomix==1.2.1', 'console_scripts', 'mcomix')() File "/usr/lib/python2.7/site-packages/mcomix/run.py", line 206, in run assert PIL.Image.VERSION >= '1.1.5' AttributeError: 'module' object has no attribute 'VERSION' [ami@xfcenew Bureau]$
This is a well known issue and reported on Arch Linux bug tracker. See here: https://bugs.archlinux.org/task/62242?project=5&string=mcomix
Upstream fixed the issue on their side with commit 486f02 in master, but have not made a new release yet (they didn't do any new release since February 2016 actually).
I do not use this application myself, but even, I still tried to fix the issue by backporting this commit in the source code for version 1.2.1. It looks like my fix works fine on my side, although I only did the test on a VM.
Here's my PKGBUILD. Consider it as a proof of concept and feel free to adapt it as you want (if you decide to make an overlay of course). https://mega.nz/#!llMxCa6L!FOtkjH9Y4KzTfvR2wxxi6WXYIHJFs4K6yF7obYF11Hw
I don't know how to download a .diff or .patch file from SourceForge, so I had to made the .diff file myself.
The build time should not be much an issue, it should be something really quick to build (it took a few seconds on my machine).
The overlay package will be needed for all branches that has python2-pillow 6.0.0, so currently Unstable and Testing (and Stable soon, when there will be a sync between Stable and Testing).
Thanks in advance.
