Error opening blueprint xml url" when deploying blueprint file on custom distribution (Karaf 4.2.2)

[abdelb <ab...@live.co.uk>]

I'm writing a custom distribution and have a feature.xml for my camel
features. I want to be able to drop a blueprint xml file in deploy/ and have
it listed as a bundle - however, I'm getting a strange error message: 

14:31:36.322 ERROR

The blueprint file is valid - I know this because if I run a non-custom
Karaf 4.2.2 and install camel, it works fine. Running feature:install camel
leads to the following features being installed: 
xml-specs-api 
camel 
camel-core 
camel-blueprint 

I have these features in my custom distribution so I can't figure out where
this error is coming from. My feature.xml looks like this (camel version is
2.23.1):

Have spent quite some time trying to fix this without any luck so far -
would really appreciate any assistance
