Try reinstalling python2-pillow

I tried that already:

[orschiro@thinkpad ~]$ sudo pacman -S python2-pillow
[sudo] password for orschiro:
warning: python2-pillow-2.2.1-1 is up to date -- reinstalling

[orschiro@thinkpad ~]$ cinnamon-settings
No module named Image

Is your /usr/lib/cinnamon-settings/cinnamon-settings.py header calling python or python2? It should be calling python2, otherwise it would be searching for python-pillow instead of python2-pillow version. The current package should change it by default to python2 as it is right now.

If you have python2 in the header, check also if you can import Image in a python2 console: python2 -> from PIL import Image

No errors:

[orschiro@thinkpad ~]$ cat /usr/lib/cinnamon-settings/cinnamon-settings.py | head
#!/usr/bin/python2

[orschiro@thinkpad ~]$ python2

>>> from PIL import Image

If I use python2-imaging instead of python2-pillow, then I can launch cinnamon-settings:

[orschiro@thinkpad ~]$ cinnamon-settings
/usr/lib/python2.7/site-packages/gi/types.py:226: RuntimeWarning: Mixin class XletSettingsWidgets.BaseWidget is an old style class, please update this to derive from "object".

Hmmmm that is weird... Check /usr/lib/cinnamon-settings/bin/imtools.py to see what are you importing. It should say "from PIL import Image"

Yes it does:

[orschiro@thinkpad ~]$ cat /usr/lib/cinnamon-settings/bin/imtools.py | grep "from PIL"
from PIL import Image
from PIL import ImageDraw
from PIL import ImageEnhance
from PIL import ImageOps, ImageChops, ImageFilter

The bug is still persistent with cinnamon-settings-daemon 2.0.5-1.

Upstream commented that you should change the dependency to python2-imaging.

See: https://github.com/linuxmint/Cinnamon/issues/2495#issuecomment-27574724

What do you think?

python2-imaging was replaced by python2-pillow, which provides python2-imaging so it shouldn't be a problem. I know that python2-imaging is still available on the repos, but I will have to consult about this. I can't reproduce your error using python2-pillow

I can't reproduce it either on my systems. I think that something should be wrong on your system, because nobody else experienced this problem.

I am afraid you are right. What do you recommend me to try?

Reinstalling the packages, as already reported above, does not resolve it.

You could try to reinstall all packages on your system. To do this, make sure that no third party repositories enabled in pacman.conf, then run the following command:
# pacman -S $(pacman -Qq | grep -v "$(pacman -Qmq)")

I'm closing this task now, but feel free to ask help on the forum.
