I've just discovered (by looking into kernel logs) that the kernel has a
NULL pointer reference -- sorry for not looking earlier. So probably a
bug in mISDN not in chan_capi.
I've attached kernel and asterisk logs to sourceforge. Do you know where
to send mISDN bug-reports?? Also interesting that it happens only with
0.4.0-PRE1 ...
Sorry, I don't have a asterisk chan_capi log -- I've moved back to 0.3.5
after my wife tried several reboot cycles to call her grandma -- and me
noticing a pattern in the logs... :-) So if you still need the logs
(even after knowing that the bug probably is in mISDN) I can provide one
later tonight :-)

Can you give me a pointer on what to read for asterisk channel
programming?

Cool. Anyway, some docs on asterisk programming would be a good start...
