Set up a debian 6 machine. Installed Trinity as instructed on web page. Kmail itself starts ok at first. then copied kmail config files, .gnupg and the mail dir itself over from a SuSE12.1/kde3 machine (kde3 from their official repos.) Launched it and it crashes saying: kmail: /build/buildd/kdepim-trinity-3.5.13/kmail/kmmsgbase.cpp:1273: off_t KMMsgBase::getLongPart(KMMsgBase::MsgPartType) const: Assertion `sizeOfLong == l' failed.
