Error in PortalCrawl Web Service (0x80042617)

This nasty error is shown in Event Viewer when Office SharePoint Search crawler process can't process "My Sites" to index the users. The unofficial workaround is to delete the SSP and re-create it again. I've found another one:

• Check that the My Sites site collection is NOT in the root (/) of the Shared Services web application. In my case it was under /mysites
• Delete that site collection
• Create a new site collection of the type "My Site host" (in Enterprise tab) in the root path (/) of the Shared Services web application
• Start a Full Crawl
