While asking haikuporter to download and enter the chroot for gcc 4.8.2
(on a gcc4 primary Haiku), I encountered the following panic:
{{{

I haven't encountered this one previously, and wasn't certain as to what
information would be useful to additionally grab out of KDL at this point.
In any case, this was the first invocation of porter from a first boot of
a new build (hrev46798), with no other apps running other than the
services started at boot. Please advise what additional information would
be of use if encountered again. If helpful, the invocation of haikuporter
was simply `haikuporter --no-dependencies -E gcc`.
