Prior to pyeval() function I was using
vim.command("let dict=%s" % python_dict)
inside python code. I think this was a standard solution to translate
python objects like dictionaries into vim language. I think it would be
nice if pyeval did the translation of keys into strings it self. This
error might occur in quite a few plugins. Otherwise it is nice to add
a comment in the documentation of pyeval().
Best,
