UID's, again, but with a twist :-)

[Magnus Therning <therning@xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx>]

My first post after 'discovering' offlineIMAP in the latest issue of
LinuxJournal :-)
I have read both the manpage and the mail discussions on the UID
problem. Now I am seeing some interesting behaviour in using mutt and
offlineIMAP together:

 The validity of the UID for folders differs between runs!

Ex, my last three executions of offlineimap gave the following:

 therning@pc67148596[~].$ offlineimap
 WARNING: UID validity problem for folder INBOX.hideya-kawahara (saved 
1074565220; got 1074565550); skipping it
 WARNING: UID validity problem for folder INBOX.olist.security.bugtraq (saved 
1074565220; got 1075342592); skipping it
 WARNING: UID validity problem for folder INBOX.sent.2003-06 (saved 1074565550; 
got 1074565220); skipping it
 WARNING: UID validity problem for folder INBOX.spam (saved 1074565220; got 
1074565550); skipping it
 therning@pc67148596[~].$ offlineimap

1074565220; got 1075342592); skipping it
 therning@pc67148596[~].$ offlineimap

 WARNING: UID validity problem for folder INBOX.sent.2003-06 (saved 1074565550; 
got 1074565220); skipping it

I am puzzled to say the least. Anyone who can offer some insight?

- You know, it's at times like this when I'm trapped in a Vogon airlock
  with a man from Betelgeuse and about to die of asphyxiation in deep space
  that I really wish I'd listened to what my mother told me when I was
  young!
- Why, what did she tell you?
- I don't know, I didn't listen!
