[GoogleCodeExporter]

What steps will reproduce the problem?
1. configure ZAP to use upstream proxy
2. go to marketplace. 
http://zaproxy.googlecode.com/svn/wiki/ZapVersions.xml?v=2.0.0 is loaded using 
the upstream proxy
3. check items marked as "update" or new Add-ons from Marketplace-Tab. 
4. Check the output-tab. files will be downloaded directly not using the 
upstream proxy.

What is the expected output? What do you see instead?
files wont get downloaded in networks were upstream-proxies are neccessary to 
connect to the internet

What version of the product are you using? On what operating system?
2.0.0 on Windows XP 32 Bit 

Please provide any additional information below.
Verified with local intercepting proxy.
