On one of my devices (similar setup, both on cssu-thumb), MyPaint works well. Hoever, on another one, I get following error:

Code:

:$ /opt/mypaint/bin/mypaint
external python-simplejson
confpath = /home/user/.mypaint/
Traceback (most recent call last):
  File "/opt/mypaint/bin/mypaint", line 172, in <module>
    main.main(datapath, confpath)
  File "/opt/mypaint/share/mypaint/gui/main.py", line 75, in main
    run()
  File "/opt/mypaint/share/mypaint/gui/main.py", line 42, in run
    app = application.Application(datapath, options.config, args)
  File "/opt/mypaint/share/mypaint/gui/application.py", line 55, in __init__
    self.load_settings()
  File "/opt/mypaint/share/mypaint/gui/application.py", line 199, in load_settings
    user_config = get_json_config()
  File "/opt/mypaint/share/mypaint/gui/application.py", line 143, in get_json_config
    return helpers.json_loads(jsonstr)
  File "/usr/lib/python2.5/site-packages/PIL/__init__.py", line 307, in loads
    
  File "/usr/lib/python2.5/site-packages/simplejson/decoder.py", line 335, in decode
  File "/usr/lib/python2.5/site-packages/simplejson/decoder.py", line 353, in raw_decode
ValueError: No JSON object could be decoded

I suspect that something related to python is wrong - device in question had serious filesystem corruption, before proper patched fsck tools become available. I thought I have fixed all results, but some lacking/messed files may remain. The thing that I'm sure about, is that there are *no* I/O errors - filesystem is fixed, so the only possible thing is some missing files. I tried reinstalling everything python-related I could think of, to no avail.

Does anyone have idea what may be causing this error, and what to reinstall to get rid of it?

Thanks in advance,

Try looking into the mypaint config files. Sounds as if some of them was broken.

*facepalm* doh. You're absolutely right, nuking /home/.mypaint and reinstalling *again* solved it.

I was so focused that it's python-related problem, that I completely skipped such obvious step. Thank you, meantime, I'll find some cartoon box to put on my head, in case I would need to go outside during daylight. Such a shaming situation...
