I added currency conversion to libconversion/converter runner and it loads 
small xml file from the ECB web site. It caches it for a day and also checks 
if network connection is active with Solid.

Does not seem to help (if I used it correctly). Until I figure out what's 
wrong KProcess::execute(QStringList() << "kioclient" << "copy" << URL << 
m_cache) seems to work (code is in svn kdeplasma-
addons/libs/conversion/currency.cpp).
