I tested the scenario you mention, but could not duplicate the
problem. In testing, if the eventlog source for an eventlog entry is
deleted, it seems to merely skip those. It didn't cause a problem on
my Windows box. Perhaps that was an NT 4 issue, or perhaps it was a
problem with older versions of the libs.
In this case, however, I've determined that it's definitely something
in the log itself. If I try to read the backup file, it crashes on me
consistently just after record number 5458.
So, now I need to figure out what the heck is up with this particular
log entry that's causing the problem.
