When I do something like this $loop(%_path%)$filename(%_folderpath%%_filename%.cue)$loop(%_path%)%cuesheet%$loopend()$loopend() -> Mp3Tag crashes... with an empty error log (except for the header - apppatch, version, etc, but no code reference), two DrWatsons are invisibly hanging around in the background and I have to kill them with Process Explorer. 
Version is 2.36
