Trophie worker processes dying at a high rate: am I alone?

Hello there,

I wonder if there are other Trophie users out there?

Recently,   my   previously   solid-as-a-rock   Trophie   has  started
misbehaving, worker processes SIGSEGVing at a high  rate.  The  master
process was staying up though, so Amavisd-new couldn't detect this and
it effectively brought our mail traffic to a standstill.  And  yes  of
course, last time it happened on a friday evening...

This caused a bunch of lines like this in the mail log:
Aug 13 23:59:59 mail-gate trophie[13034]: SIGNAL [11] caught - cleaning up and exiting.

I haven't changed much on this box lately (Linux RH 7.3 in self-update
from  source mode now). Of course my trend-update.pl script did change
to  (partially  at this time) manage the new numbering, but well, it's
still  just  downloading the VPNs so I can't see how this would be the
reason.  No,  this  machine  isn't running my hacked Trophie yet. It's
still using the vanilla 1.12.

Anyone else experiencing this? Just to know if that's something  local
to my set-up.

Greets,
_Alain_
