I am not sure if I'm sposed to post LFS panic's here, but have seen others
do it. I'm supposing a PR would be bad since a user like me can't tell
Bug #2 from Bug #5 by looking at a backtrace, so the relationship between
closable PR's and bugs is lost.
Is there someone who wants to receive these? Does anyone want them at
all, or are they unhelpful and I should shut up and let LFS simmer for a
while? Someone let me know if I should do otherwise than I'm doing now.
