Marco, fyi, there's really no reason for you to confirm this. You were the
one who reported the bug so it is a foregone conclusion that you would claim
to confirm it. Confirmation is something more useful when a third party can
independently confirm a bug. Of course, there are exceptions to this rule,
for example, I confirmed some of my own bugs when I turned on new pylint
flags, but that would be verifiable by anyone.

Junior, could you tell me the exact name of the file, with the special characters and all? I'll write a test case for the new indexer to make sure it works properly.

I have the same problem. The error about the unicode strings is thrown in the isDirectoryInCache(self, path) method of the ImageCache class.

entertainerlib/backend/components/mediacache/image_cache.py

I have added a print statement at the beginning of the function, printing the content of the path variable. The function is called without problems until the file name is "Königreich der Himmel" which contains the german umlaut ö. Python prints the filename as "Königreich der Himmel". So the problem seems to be due to non-ascii characters in the path.
