[rt-users] mailgate throws up on valid message

I agree, but I had included more information into the second message as 
we were debugging the issue as well. An unmodified resend is surely a 
waste of time and bandwidth.

Understood!

I have included the dynamically created /var/opt/... file from 
HTML::Mason where the error occurred. This is a state file - no source code.

That's why I send the second message. The original message contained 
information we cannot disclose. "Sanitising" it removed the problem - 
the mailgate worked on the sanitised message. Once we had a second 
message I can disclose, I was able to append it to the second message. 
Therefore the re-send.

I have added all what is in the logs. Even with "debug" level enabled, 
the was nothing else.
That's the strange thing: the REST mailgate suddenly stopped and 
"message" was not assigned any value. No, it's not the request body 
size, that was the first thing to check :-)

I thought it's some special character in the message, but all characters 
are encoded, so I am at a loss for the cause.

"Snooping" the traffic we see the rt-mailgate send the full message and 
the REST gateway receives it, but when checking the "message" variable 
at the very next line in the REST code, it's undef :-(
