I prefer Gnome to KDE generally, but there are some KDE apps that are really
nice so I install and run them on my gnome desktop.  I know that means some
library duplication and probably various kinds of overhead,  But that is the
extent of my knowledge.  I don't see any obvious negatives so far though
this is a 3.0 GHz P4 with HT on 1 GB ram so should have plenty of horsepower
for such things.  But ...

1) Might I lose any functionality running the KDE apps under Gnome?
2) Are there definitive caveats or known problems doing so (or a list
somewhere)?
3) Is there any way to get an idea of how badly resources are being wasted?

Specific example: Comparing AmaroK to Sound Juicer is like comparing a 67
Corvette to a Model T.  But when I was looking through preferences I got a
report that there had been an error running/accessing/??? aRTs (sic) for
AmaroK.  I ended up turning it aff and I can't even find out what it is.
