Status: VERIFIED DUPLICATE of bug 167320

Just imagine, that mozilla itself was set as a helper application for some
mime-type or extension. Then when trying to open file of this type mozilla start
to open new window in infinite loop.

Reproducible: Always

Steps to Reproduce:
1. Set Mozilla helper apps for some strange mime-type (extension)
2. Open file of this type in Mozilla
3.

Actual Results:  
Mozilla start to open new window in infinite loop. Kill parent window (or
quickly close all windows)

Expected Results:  
Hard to tell, realy. I see tree possible solutions: 1) prevent user from setting
Mozilla as helper, 2) open such files as text-plain (so new window would not
open file in loop), or maybe easily give message to user when user try to set
mozilla as a helper, that it is not safe.

Confirmed.  I had this happen once.  I believe the extension was .SGML or
something similar.  Got stuck in a nasty loop with dozens of windows open.  Had
to kill it hard then unset the association.
