one more (but different) trap 12

Hi Rob & list!
I've got another trap 12 (well, that's not really surprising - I've had
at least 8 since midnight).
The other traps (my guess from the function names listed by a db trace)
were somewhat related to the network. This one isn't. It's happened a
few seconds after connecting by ppp (ISDN).
Here we are:

cvsuped on monday.
I've got this dump on disk, too (for the case you need some more infos).
Also I wanted to try an `addr2line -e
/usr/obj/src/sys/BELLONA/kernel.debug` (trying an address from a panic
before) but all I get there is output like ??:0. What am I doing wrong?
Still don't have debug symbols / line numbering in my kernel? I've never
used addr2line before, so please tell me if I did something stupid.
