[Dovecot] 1.1.beta11 crashes

[Brian Taber]

I am running 1.1.beta11 because I was having locking and coruption 
issues with indexes and mailbox on the latest release version.  Some of 
my previous corrupted indexes caused an issue with 1.1.beta11:

I removed the index files for that mainbox and that error went away, but 
it caused another error:
Dec 20 21:45:29 ra dovecot: IMAP(bodil at mydomain.com): 
file_dotlock_open() failed with file 
/mailindex/mydomain.com/bodil/.INBOX/dovecot.index.log: No such file or 
directory

I had to recreate the .INBOX folder manually and all was great.  The 
funny thing is it had already created all the other folders in the 
mailbox....
