Fetching images for large playlist fails.

[adamcik]

Loading my 2000 track playlist in mopidy-mobile triggers the following error. I'll try and get some more debug details this evening. This was on master, not by modified code with playlist image support.

This looks like #171. I don't think we have the same market but 3wQtzisWD2KTvgii3FjSJ0 seems to be relinked to 54WcX7oBwRRr8ngamUnQhV.

[adamcik]

Sounds very plausible. Closing since it's dupe then.
