After getting hammered by last night's lovely round of trackback spam, I upgraded my 2.661 blog to 3.15 for the improved management features. I pretty much did a fresh install, retaining my old mt.cfg file and running the updater scripts, but otherwise installing as if new. So everything should be squeaky-clean.

Upon attempting to rebuild my individual archives, I ran into the following error after successfully rebuilding batches 1-40 and 41-80 (so there's something fishy going on somewhere in entries 81-120, I guess):
CODE
An error occurred:

Can't use string ("") as a subroutine ref while "strict refs" in use at lib/MT.pm line 1193.

Use of uninitialized value in subroutine entry at lib/MT.pm line 1193.
Thanks in advance for any help.
