Wow, this was quick.  Tomorrow, I'll test it and report back if the bug
is gone.

I already reported the bug as #2272, and Andreas checked in a fix for
it.  At that time, I couldn't reproduce it, but out of sudden, it hit me
again, and David Engster found out that it seems to be triggered when
the mode-line is updated.  He got the error because of `display-time'
and I got it when `rcirc-track-minor-mode' updated the mode-line.  So
since Andreas last fix, the update of the mode-line was needed for me to
trigger the bug again.

Bye,
Tassilo
