That's what it should have done. I just tested and it did successfully update the index file without complaining about anything again. Anyway I added some more checks to the code now. > Also, from the code (virtual_sync_ext_header_read in > src/virtual/virtual-sync.c) it seems that the last mailbox should be skipped > because of this error, but the mailbox works fine.

I tried stress testing by having it open "*" mailboxes and then randomly creating and deleting them. Didn't seem to cause broken virtual index file.
