error when generating from command line

Hi Guys.

This is my process:

1.  The xrc is created by hand.
2. pass xrc through xrc2wxg.py to generate wxg
3. pass the wxg file through wxglade.py to generate cpp/h files

All of that is in a oneliner command.

With a previous version this worked flawlessly.

Now I am getting this:
--8<---------------cut here---------------start------------->8---
Exception type:      <class 'xml_parse.XmlParsingError'>
Exception details:   'language' attribute missing: could not generate code _((line: 3, column:  0))
--8<---------------cut here---------------end--------------->8---

I understood it is because the xml "application" tag does have the "language"
attribute, but in the past it was not necessary, as the command call
have the required parameter see:

--8<---------------cut here---------------start------------->8---
python2 ~/opt_clone/wxglade/wxglade.py --generate-code=C++ --output=~/xrc/StockTakeActionFrmDsgn.cpp ~/xrc/StockTakeActionFrmDsgn.wxg
--8<---------------cut here---------------end--------------->8---

this is the  wxg output:
--8<---------------cut here---------------start------------->8---
<?xml version="1.0" encoding="UTF-8"?>
<!-- generated by xrc2wxg.py 0.0.5 on Tue Nov 17 15:08:02 2015 -->
<application encoding="UTF-8">
    <object base="EditFrame" class="StockTakeActionFrmDsgn" name="StockTakeActionFrmDsgn">
        <size>200,200</size>
        <title>Stock Take Action</title>
        <style>wxDEFAULT_FRAME_STYLE|wxTAB_TRAVERSAL</style>
    </object>
</application>
--8<---------------cut here---------------end--------------->8---

this is the reduced xrc:
--8<---------------cut here---------------start------------->8---
<?xml version="1.0" encoding="UTF-8"?>
<resource version="invcross">
  <object base="EditFrame" class="wxFrame" name="StockTakeActionFrmDsgn">
    <size>200,200</size>
    <title>Stock Take Action</title>
    <style>wxDEFAULT_FRAME_STYLE|wxTAB_TRAVERSAL</style>
  </object>
</resource>
--8<---------------cut here---------------end--------------->8---

Is this the expected behaviour?

Best Regards
