[hobbit] Slightly OT: External Perl Script

Hi,

I'm no perl guru, but it seems that the double quotes in your text 
aren't masked with escapes any more while your message is interpreted by 
the hobbit server. So hobbit doesn't know what to do with the rest and 
the shell tries to deal with the rest. Perhaps give that a try: replace 
all \" by \\\"

Rolf
