No, at least I don't find any occurence of either of those in the imap log.

Would you be happening to use Cyrus also, with CONDSTORE enabled but 
MODSEQs disabled (e.g. Bug #9796)?  Because this simply should not 
happen:

"cacheid":"V1233013246|U75950|M-57|9|0"

That is saying that the status return for the mailbox is reporting -57 
messages.  I can't even begin to reproduce this.

That being said, the error reported is because the thread data was 
returned as an empty array which was converted by json_encode into an 
array.  However, viewport is expecting this to be a hash.  Thus, the 
solution is to always cast the thread return as a a hash.

I'll postpone committing this until the releases are finished.

And for completeness, the deleteMessages request and response right before:

This should have been the response that caused the error:
