I was able to reproduce this as well. I have no clue why this happens, 
but I filed a bug about this:
http://mapserver.gis.umn.edu/bugs/show_bug.cgi?id=479

Please add any more information you may have to the bug.

BTW, I don't think it's MapServer that's wrong in *thinking* that it got 
a 500 status ... I think it's more that the remote server doesn't like 
the request that MapServer sends and really does produce a 500 error.
