Top-level INBOX not syncing

[Aidan G. <aid...@fa...>]

I am using isync to keep a local archive of one of my gmail accounts, 
and I just today noticed that messages in the top-level "INBOX" mailbox 
on the remote are not ending up in the local maildir store, and I get 
this error when running mbsync:

Error: channel gmail, near side box INBOX: Unable to recover from UIDVALIDITY change.

My .mbsyncrc file is as follows:

MaildirStore local-gmail
Path ~/path/to/gmail-mbsync/
Trash Trash
SubFolders Verbatim

IMAPStore gmail
Host imap.gmail.com
SSLType IMAPS
Us...@ex...
PassCmd "pass Gmail_mbsync"

Channel gmail
Far :gmail:
Near :local-gmail:
Create Near
Expunge Near
Sync Pull
Patterns * !"[Gmail]/All Mail" !"[Gmail]/Important" !"[Gmail]/Starred" !"[Gmail]/Bin"

How can I fix this?  All other folders appear to be synced as expected.
