#18 MComix 2.0 only works with Root

[Finder X]

Hi, I using the linux version of MC 2.0 and the only way is running correctly is using sudo or su.

When is execute with normal user this happens:

Looks like a bug related to the GTK3 conversion. The thumbnail background color is stored incorrectly in ~/.config/mcomix/preferences.conf. Maybe a relict from old preferences? Could you post which values the key "thumb bg color" is currently set to?

As a workaround, you can delete the key "thumb bg color" in this file, and MComix should start up again.

Hi, I try removing "thumb bg colour" and a similar error occurs, next I removed "bg colour" and MC open fine. Yes :). Thank you.

Now I have this new errors, I can't open any file:
This one is when I try Open > browse some file and try open one zip file with images into it.

Next I try open the library and this happens:

For make sure, I used the mcomixstarter.py and after all those error, I try

python3 setup.py install --single-version-externally-managed --prefix /usr --root / --record mcomix-files.txt

Both have the same errors.

Strange, from what I can see all the test ZIP archives from the MComix test cases work. Could you start MComix using the command 'mcomixstarter.py -Wall'? The '-Wall' parameter enables additional debug output, in particular stack traces for all error messages. Please provide these stacktrace messages so I can look into the problem.

Thank you, I received the log messages, which I have removed in order not to clutter the issue. Seems like there were still a number of unfortunate problems left from the Python 2 -> 3 conversion. I have committed some fixes, which should address the issues you mentioned.

Thank you, let's hope that in the next version they are fixed.
Regards.
