What is QLThumbnailErrorDomain Code=110?

Hi,

when generating thumbnails I sometimes see the error "QLThumbnailErrorDomain Code=110". This happens to files which can be processed when trying again, so it is not an issue with the files in general. I could not find an error with that code here. Any ideas where to look and/or what causes this?

Thanks, Michael
