[horde] Error in the logs when searching from field

[Mike]

I did a search (in the from field) on my server and found this in the logs:

[imp] [search] There was a temporary issue when attempting this  
operation. Please try again later. [pid 189484 on line 731 of

Let me know what else you might need.

This is not yet production, so I can apply specific commits.
