clipperz fails to export on corrupted card

[jokajak]

if there is a corrupted card you cannot export your other cards

The current behavior is wrong, but I am not sure what would be a better one.
A possible solution is to export all cards that can be successfully processed, raising a very visible warning if some cards processing failed.

the behaviour I'm seeing on my instance of clipperz is that it just stalls exporting, no error message or anything. I had to delete the corrupted card before I could export
