SQL in create_page_browser fails with sqlite

[Lem]

I'm running the lastest master and using sqlite. On visiting list-virtual.php the following error gets created.
Placing a var_dump in functions.inc.php to look at the $idxfield (line ~550) reveals that the variable got address, which of course can not be exploded into two elements. So $end can not be filled and the SQL query fails.
