automatic anti-RMT filter catching non-RMT messages?

[synesthetic]

Just had a strange episode in a linkshell.
One line my brother said didn't go through to anyone else in the linkshell. I thought he just forgot to say something, so I asked him to clarify, since he's in the same room as me. After confusion, discussion, viewing each other's screens, and repeated attempts to paste the line that no one else seemed to get, I'm thinking that the line is somehow getting caught as RMT-spam.

The specific line in question is..

"Going to log and shut the computer down. Computer needs a reboot... But I still think that the HDD might be dying."

Probably difficult to tell but.. has this sort of thing happened to anyone else?
Anyone have any clues on what in that benign statement could be getting caught on the filter?

edit: A few hours later, this was our guess:
