mtn: fatal signal: Floating point exception
this is almost certainly a bug in monotone.
please send this error message, the output of 'mtn version --full',
and a description of what you were doing to address@hidden
do not send a core dump, but if you have one,
please preserve it in case we ask you for information from it.

  Generated from data cached in the distribution;
  further changes may have been made.

No debugging info (this mtn is my /usr/bin one via Gentoo portage) so
I couldn't get a backtrace, and I'm not feeling like dealing with
building nvm head right at the moment so someone else can do it or
eventually I'll get to it.

Obvious guess: division by zero in computing the percentiles.
some_timestamp / (# checkins - 1) or suchlike.

After second checkin, no problem.
