>From what i gathered at a quickl glance:
Test security update, rel 2.1 is being jnstalled
Updated then to rel 5.1
Test security package is uninstalled
Rollback
The test now expects release 2.1, but this is not found

I chekced snapshot 0502's qa test (currently published snapshot) and that
failure was there too - but from discussions it was believed to be a followup
error. Since the other failures are now resolved, and this failure still being
present, that assumption was obviously wrong
