I believe this is the same bug that we hit in the ASET
labs:

Bug Details for CSCse44052
Crash when config IPv6 interface distribute list

Symptom:
Router crashes when an ipv6 prefix-list referenced by
a RIPng distribute-list is created or changed.

Conditions:
The crash will occur if the following order of
configuration is followed:

- RIPng is configured to use a per-interface
distribute-list.
- The prefix-list referenced by the distribute-list is
subsequently created or modified.

e.g.

ipv6 router rip test
distribute-list prefix-list bill out e0/0

exit

ipv6 prefix-list bill permit ::/0

Workaround:
Ensure that the IPv6 prefix-list is configured before
the referencing distribute-list

HTH
