Mark Tinguely has found the offending timer.
The following patch fixes the problem for me:

Printf is fired with the patch applied, and panic doesn't occur.
I have tested it on -current cvsupped with date=2005.10.21.16.25.00,
and will test it on the fresh -current (in a day or two - I will need
to recompile everything). The patch should work there
although. According to the cvsweb, mld6.c didn't change.
