Issue:Output nothing if using include in parser function version of DPL within template

Problem

When I use parser function version of DPL within a template, the "include" function will make the whole wiki page output nothing (i.e., empty HTML), and there seems no error in MediaWiki's debug log. I use it like this:

{{#dpl:
|category={{{1}}}
|include=#SomeSection
|titleregexp={{{2}}}
|format=,<h2>'''[[%PAGE%|%PAGE%]]'''</h2>
}}

1. If I use debug=5, I can see the non-parsed Wiki text output correctly.
2. If I use it individually (not within the template and replace those variable), it also works correctly.
3. If I remove "include", it works.
4. Since I have to pass parameters, I can only use the parser function version.

My MediaWiki version: 1.13.0. Is there any clue I can investigate further? Thanks!

I guess that you have a problem with the regexp.

The following example works correctly (here, using MW 1.13) as you can see:

{{test get chapter|fictitious country|.*un.*}}

#1 = fictitious country
#2 = .*un.*

{{#dpl:
|category={{{1}}}
|include=#Religion
|titleregexp={{{2}}}
|format=,<h2>'''[[%PAGE%|%PAGE%]]'''</h2>
}}
