That seems like a likely explanation. It definitely wasn't in the clipboard though (I had opened the script as a reference in a separate tab but I hadn't even looked at it yet, and the part of the script that the gtk terminal reproduced was several pages down).
Since it gave me 302 chars and I was generating boxes of at most 255 chars, I suppose this is the only possible culprit. Maybe I should generally avoid displaying random sequences of characters in gtk if there is this risk.
