Verbose warning about SafeControls - safe to ignore?

Feb 18, 2010 at 12:14 PM

I'm testing the wizard as a way of transferring documents in one document library to another. The destination is in the same site collection. (Ultimately it will be in a different web application on the same farm.) I'm using the command-line interface as the intention is to set this up as an automated daily or weekly copy.

In the export log I'm getting the following warnings:

[2/18/2010 12:52:02 PM]: Progress: Exporting File schoolpersonnel/forms/Documents/Forms/AllItems.aspx.

Obviously these are the built-in forms so I don't think it's related to any custom code of ours.

The import log has two warnings which sound as if they could be related.

[2/18/2010 12:54:55 PM]: Warning: Could not find WebPart [Unknown: 2242cce6-491a-657a-c8ee-b10a2a993eda] in the safe controls list.

Despite this the import/export process seems to go OK and the destination document library still works as expected. Does anyone know how to fix whatever the messages are complaining about, or, failing that, does anyone know if they can safely be ignored?

A similar operation, but running between two separate single-server farms (both test boxes), doesn't have those warnings but does have this:

[2/18/2010 1:19:41 PM]: Warning: Could not find WebPart Microsoft.SharePoint.dll v2.0.50727 in the safe controls list.

I tried adding entries to web.config, copying the v12.0.0.0 Microsoft.SharePoint.dll SafeControl entries and changing the version number. It had no effect.
