 The {{{Variable}}} class does not accept empty constants ("") in
 templates. The error message is:
 {{{
 Could not find variable at start of ""
 }}}

 I traced the error to the {{{__init__}}} method of {{{FilterExpression}}}.
 The attached diff fixes the error. I think some of the surrounding {{{if
 <var>}}} statements should also be rewritten as {{{if <var> is not
 None}}}, but the diff is restricted to fixing this bug.
