Forum OpenACS Development: Strange bug in the search package

I have the search version 5.3.0b1 installed, but I use OpenACS 5.2.3. I can see there's a very strange bug in my search package. When I try to search the words "php" and "mysql" the following error appears to me:

invalid command name "::0"

Sometimes I have a different one:

It seems like the first error happens when I try to perform the search in a new page, where I didn't search for anything yet. The second one happens when I try to perform a search in a page with some search results, and I try to search for new ones. I have a dinamic portlet in xowiki that brings me the latest-portlet (with the last contributins in the community), the community name and description. I've created a page in xowiki wich includes the portlets, and the page must receive the community_id. The only place I think there can be such words is inside that page. Do you think there's anything to do?
