Created attachment 28449 [details, diff] mobile IPv6 protocol dissector patch
Created attachment 28451 [details] capture file to reproduce the crash
This patch will be included in the future versions of ethereal, as it is already commited to CVS, but I think the patch should be included in the currently available ebuilds.
this is fixed in 0.10.4 (which is in portage).
