picard 1.4.1 sometimes goes into an infinite loop with the following error repeating in the error log:

Traceback (most recent call last):
File "picard\album.pyo", line 585, in update_metadata_images
File "picard\util\imagelist.pyo", line 98, in update_metadata_images
File "picard\util\imagelist.pyo", line 46, in _process_images
File "picard\coverart\image.pyo", line 212, in _eq_
RuntimeError: maximum recursion depth exceeded in cmp

I have attached the complete picard.exe.log. I'm using just default preferences and NO plugins.
The error seem coverart related.
