[imp] IMP Emtpy Trash bug?

[AJ]

Hello,
  I am using the latest CVS snapshot of both horde and imp and I get a 
strange little bug when I try to empty the trash.
If I read a message and hit the delete link in the message, then try to 
empty the trash I get an error that says:
There was an error viewing the requested message.

I get that under the message that the trash was emptied.

Anyone know what could cause this?

Thanks.
AJ
