This is when running under valgrind:
<no crash, logs at

I tried to HAMmify several sets of emails

this is when running without valgrind, the first selection of three emails als ham surprisingly worked, the next selection of 8 or so failed (was meaner in my valgrind tests, and I started that kmail beast twice):

Good luck!

My very personal hunch is that valgrind's default settings prevent the missinterpretation of some undefined variable of which there are many reported. Well, ... enjoy.

Many thanks for looking into this

The system is the latest from unstable and experimental.
