Comment 5 for bug 7848

The symlink bombing thing was due to having a stray symlink, at which point XKB
couldn't generate a complete map for Mac; it tried to collect one of the
elements, and instead of failing gracefully, it tanked.

To me, this looks like it couldn't find this 'hpi6' variant, which is a HP
Internet Keyboard; looks like a custom type to me.
