[rt-users] Mailgate doesnt generate tickets after Upgrade

[ms at fv-berlin.de]

Hi,

I just updated an old 3.8.4 RT to 4.2.3 and from what I can tell the
actual RT system works fine, fulltext search is up and running... but
the mailgate seems to unable to create tickets. heres the
apache2/error.log section:

To me this looks like the mailgate tries to create tickets with IDs
starting from 1 instead of using an unused ID and subsequently
everything else associated to this ticket creation (Role/Group creation)
fails too, but maybe I am looking at this the wrong way. In any case,
feedback is greatly appreciated.
