An OpenPKG instance I've recently upgraded to RPM 5.1.0 first worked
just fine for a few days and today I noticed that on a simple "openpkg
rpm -qa" I get mostly all packages in the output but near the end of the
output I receive:

| error: rpmdb: skipping h#     157 region trailer: BAD, tag 256 type 256 offset -256 count 256

So, seems like an entry of a package in the RPMDB crashed for totally
unknown reasons. There was no system crash or any other package
manipulations recently, etc. Hence I've no clue how this can happen and
I see it the first time.

I fixed the problem for me with a full BDB based dump/restore of the
database, followed by a "rpm --rebuilddb" and a "rpm -i --justdb" of the
single lost package. Nevertheless I wanted to drop you a note about this
here. I can provide a copy of the RPMDB (in the state before I fixed it)
in case someone like Jeff wants to peek at it in more detail...
