I can't even *begin* to guess how something like that could happen due to kernel issues.
The signals you see are TTY signals, but SIGINT/HUP really don't make sense as a tty layer bug either. If it was *just* SIGHUP I'd think it was some tty refcounting issue, but with different signals that sounds very very unlikely.
Quite frankly, from those symptoms I'd suspect the terminal program being confused over a kernel issue. Of course, it could be a kernel change that in turn confuses a terminal program.
