Gmail imap search does not get all messages.

[Bart Kastermans]

I am trying to use imaplib with gmail.  I am finding however that with
the gmail server imaplib.search does not give the correct answer.  See
the below traces (k is a server a my department, i is gmail).
k has 6 messages in the INBOX
i has 3 messages in the INBOX

However i.search(None, "ALL")
only gives as answer "1 2", missing the third message.

Any suggestions about what I might be doing wrong?  Or is this a known
issue?  I couldn't find anything by googling, but maybe I am using the
wrong search terms.

Best,
Bart
