the scripting API does not allow opening of random files. all the access goes 
through existing plasma API to ensure that it's always correct and in sync 
with what the plasma based application expects. one of the requirements of the 
scripting API is that it produces results that work, and so there are some 
constraints such as this one.

it's not that they are starting too quickly, it's that they haven't 
implemented Plasmsa::Applet::configChanged(). we've gone through and fixed the 
ones in svn for 4.5 (with a few outstanding ones left, e.g. folderview.. but 
those will also get done..)
