We recently had a request submitted to our RT system (version 4.0.4 on
a Linux Mint 13 box) that caused a crash. I have narrowed this down to
the fact the e-mail had a header that read "Content-Type: TEXT/PLAIN;
charset=X-UNKNOWN; format=flowed" and this caused RT to crash:
cse-rt ~ # cat emailmessage | /usr/bin/rt-mailgate --debug --queue
general --action correspond --url https://cse-rt.unl.edu/
/usr/bin/rt-mailgate: temp file is '/tmp/E0FHMLj0Le/l_8jE5Tohr'

RT server error.
The RT server which handled your email did not behave as expected. It
said:

As far as I've been able to determine, any message with the header in
question causes a crash. I have not been able to determine how the
"X-UNKNOWN" header was added, but the original mail client was a recent
version of Alpine.
