open it by typing in file://(filepath) in the address bar
Doesn't do anything for me this way.(In reply to comment #8)
it also crashes when you open the attachment by clicking on the link in this bug report
That's a crash I can confirm. Not sure if it has anything to do with actual file contents though.
