- when there is an email with a very long title, the created filename is too long for the Windows Vista to read (it reports that it cannot read the file and will, in effect, not 'restore' it again); filenames should just be message ids imo
- some dates in emails are not interpreted correctly and that messages are show as being from 1970-01-18 (and they are restored as being from this date)
- when restoring labels for a large number of emails (~12000) gmail drops the connection at some point and only 5-10% of the labels are restored; there is no way to restore the labels again, restoring all emails again does not help
- there's no way to just restore the labels (there should be such option, really); we could then, for example, copy emails in outlook express via IMAP from one 'all email' folder to the 'all email' folder on gmail and then restore only the labels
- in gmail when there is one email in coversation with label, all emails share this label; when backing up and then restoring to another account some emails are left without the label; they are left out of the conversation in effect)
- when dealing with large number of emails (again, about 12000) it skips some (about 1-2% of all emails; randomly; I did not find a pattern)
- specifying any DATE (before/since) as 1970-01-01 or lower results in strange errors
