I like to use the Create Catalog feature of Calibre and haven't had any problems until latest release (0.7.36), I didn't change much except added custom column to be added to comments and then hit apply and create catalog.
The catalog keeps aborting and gives the following error message, I gather something is wrong with thumbnail cache but I am not catching what is wrong or even more important how to fix it.

If someone could clue me in, I would really appreciate it. I love the catalog feature.
