That is true.  It's not a real solution though - this is a bug.

The trouble with having a global size limit in Thunar is that some files 
are meant to be big - like video files (where just one frame will be 
extracted for the thumbnail).  The limits really have to be decided on a 
case-by-case basis for each mimetype.
