HELP! Gmvault re-started restore from beginning (?!!?)

[gitasong]

After several weeks of backing up and restoring one Gmail account to another, Gmvault suddenly and without warning seems to have re-started the restore from the beginning (?). This seems to have been triggered by a whole mess of quarantined chat e-mails in a row. The number of e-mails to be restored suddenly went from a low of 2391 to 248370 after resuming the restore. The relevant log portions are in this pastebin:

Please help! I'm running out of space in my working Gmail and need to get all of these e-mails copied over to the new account before I do! Thank you!
