Error EventID 3083 - Microsoft SharePointPS Search Service

[Vista Tester]

My system is logging this error ID once every min. That's not real good for
the system response. Any idea what's going on?

I did a search through the registry and found some details which may be
related:
Windows Search Service Office Outlook Protocol Handler
Windows Search Service PST Protocol Handler
The folder:
E:\ProgramData\Microsoft\USearch\Data\Applications\Windows\GatherLogs
The entry {9E175BAF-F52A-11D8-B9A5-505054503030}
The key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\USearch\Gather\Windows\SystemIndex

It's definitely related to the file indexing process. When I turn off file
indexing, ther error message stops.

Any suggestions on debugging techniques?

I've already done the following:
1) Deselect all included index folders: error stops
2) Turn on just one folder: errors restart
3) Regenerate index
4) Check/repair drive errors, defrag drives, regenerate index
5) System in-place update

Is this a system bug?
