Recently active topics in Ma.gnolia tagged with tag

In a bookmark I created I added a tag that included a forward slash ("i18n/l10n"). When adding subsequent bookmarks, this shows up in the tag cloud as a backslash, which is then used if I click the tag. Going back in and editing these bookmarks to use a forward slash again makes no difference to which is used in the cloud.
Curiously, entering either form in the search box appears to make no difference, and bookmarks with both forms are returned in the search results.

When I try to search for sites tagged with a certain term in "everybody's bookmarks", the site takes ages to actually return (or doesn't return at all). This seems to only affect the global tag-pages. At least when I try to view a tag-page within my own collection, it works well.
