using debian sources from ubuntu

[tom arnall]

some questions on using debian sources for ubuntu intrepid system

	is it safe? i would prefer to do without something 
	than risk dependency problems
	
	if so, should i be using lenny/testing sources only?
	
my immediate need is to install kcontrol so that i can -- 
hopefully -- control the format of times displayed for kalarm 
items. apparently this is not available from the ubuntu intrepid 
sources, since it doesn't appear in the synaptic choices.

thanks,
