I upgraded my wiki to 1.5.1 this weekend and I noticed queries relying on the '~' LIKE operator are now returning empty results.

For example, this query used to work :

{{#ask:[[Category:Company]][[Has page name::~A*]]
|template=Row A-Z Index

'Has page name' is a String property.
Adding '~' to $smwgQComparators has no effect (it used to be declared there since it was not defined by default).

Am I missing some new behavior ?
