Bugfix for custom group slugs.

If your group slug is not the default “groups”, editing or deleting categories from Group Documents of the group admin will result in a 404 page.

I fixed it by going to line 105 of the buddypress-group-documents.php and changing:

$bp->current_component

to:

bp_get_groups_root_slug()

Hope that helps.
