[reSIProcate] failed assertion in ExtensionHeader.cxx

[Lorenzo]

Hello,
I need to define a new header and I want to use the extensionheader 
feature of resiprocate, but when I wrote:

static const resip::ExtensionHeader h_Path("Path");

(like you propose in the wiki at : 
http://warsaw.sjc.purplecomm.com/wiki/index.php?title=Use_Overview#Extension_Header)

I've got a failed assertion at ExtensionHeader.cxx:25 ( 
assert(Headers::getType(mName.data(), mName.size()) == Headers::UNKNOWN); )

I use resiprocate 0.9.0.

Thank you,


Lorenzo
