[maemo-developers] Override camera application ?

[From: Attila Csipa]

Is there a simple/recommended way of overriding the camera application, like 
temporarily disabling the auto-launch on cover open, or launching a different 
app ? I'm talking about civilized, intended ways of doing this, not by 
butchering startup scripts :) There were hints on irc that some gconf magic 
could be used, but nothing more substantial and guick grepping on camera did 
not yield substantial results.
