possible assign + multiple modifiers bug

Hi, I'm still in the process of upgrading my 2.3.1 code to version 2.5.x and I ran into another difference which may be a bug. Multiple modifiers in assignments seem to go wrong: This code works like it should: {assign var="testing" value="Modifier test"} {$testing|lower|spacify} Results in: m o d i f i e r t e s t Which is as designed. The following code however: {assign var="testing" value="Modifier test"} {assign var="moretesting" value=$testing|lower|spacify} {$moretesting} Results in: Modifier test|lower|spacify Which is incorrect: in 2.3.1 both modifiers are executed. Placing quotes around $testing|lower|spacify makes no difference. Using a single modifier as in the line: {assign var="moretesting" value=$testing|lower} results in: modifier test (note the lowered 'M' of modifier) So that works correctly, it seems only to go wrong when using two (or more?) modifiers.
