No setApplicationProxy as I have written it in qgisapp is for http
proxying not socks and as far as I know its working for proxy users
using e.g. wms plugin, wfs plugin etc.

http://www.riverbankcomputing.co.uk/static/Docs/PyQt4/html/qnetworkproxy.html
has some examples and further explanation.

Shouldnt you create your app first, and then set the application
proxy? Just a thought....

Ya its not nice which is why I implemented the application wide proxy rather.

I dont have any hard evidence, but perhaps the issue is caused by the
python bindings across the plugin interface rather than the set
applicationproxy per se. It would be interesting if you tried from
within your python plugin to getApplicationProxy and see if it matches
the settings you gave in qgs options....
