Good day!

Seems I find issue on heroku with ruby rexml lib.
It is described and have ticket on rexml site:

http://mail.gna.org/public/xmpp4r-devel/2008-07/msg00017.html
http://trac.germane-software.com//rexml/ticket/165

I have such problem with xml parsing in my app on heroku

Log:

REXML::UndefinedNamespaceException (Undefined prefix gphoto found):
    /usr/local/lib/ruby/1.8/rexml/parsers/baseparser.rb:389:in `pull'
    /usr/local/lib/ruby/1.8/set.rb:189:in `each'

    ...

I notice problem during parsing xml feed from
http://picasaweb.google.com/data/feed/api/user/mike.pozdnyakov?kind=album&access=public
It is valid picasa web album feed.

Also I have no any problem with rexml from ruby on my local system and
with my app:
Ruby Installer for Windows
Ruby Version 1.8.6 (2007-12-14 Release 26)
Installer Version 186-26

Could you help me to solve this issue? Is it valid ruby lib issue?
