problem with one user after a crash

[David Lang]

I has my home mail server crash, and after the crash, one user (me) is unable to 
acess any folders.

When I manually telnet to the IMAP port, I can login, I can list and run other 
commands, but as soon as I do a select of any folder (mine or any other shared 
folder) I get disconnected.

Other users have no problems accessing the same folder.

This is with Cyrus 2.2 on Ubuntu (I need to upgrade, but have not had the time 
to do so yet)

Any suggestions on what may be wrong and how to diagnose this?
