[Dovecot] Crash with 1.1alpha2 when lazy_expunge is enabled?

[Rich at Whidbey Telecom]

I'm seeing a crash in 1.1alpha2 when trying to expunge a folder when 
"lazy_expunge" is enabled:

namespace private {
   separator = .
   prefix = .EXPUNGED/
   location = maildir:/mailstore/%u/Expunged
   hidden = yes
}
...
lazy_expunge = .EXPUNGED/ .EXPUNGED/ .EXPUNGED/

Commenting out "lazy_expunge" prevents the crash and mail is expunged.  
It happens with and without ACL's. Attached is the log output. 

The messages never actually get moved to the "Expunged" directory, but 
there is a "temp" file created each time:

/mailstore/testuser/Expunged/

Lazy expunge works on our production 1.0.0 systems.  Anyone else seen this?
