Note the huge .5GB files, which according to build-id and file size are most likely identical, but they aren't hardlinked.  Seen in F17 and F18.
I couldn't find where the thunderbird-devel-* libraries are actually shipped, so either you should be able to remove that directory before find-debuginfo.sh is run, or at least hardlink them together.  There are a few small *.debug files alongside of these, but as they are small they aren't as important.

Discovered while testing dwz utility and wondering why it needed so much memory on this package - the two .5GB identical files not hardlinked together result in
attempt of sharing most of the DIEs in it in a common file.

Will be fixed in next security release.
