I much prefer the solution Havoc pointed out in another email (which I 
read only after having replied here):

use an external program that would do the auto-launch or read the 
property. Then we'd have no dlopen trickery to open the libX11.so file. 
It would be a build-time decision whether to create this executable. And 
it would be up to distributors to decide whether they want to break their 
dbus packages into one that doesn't require X11 and one that does.

The disadvantage is that, for each program that uses the bus, one extra 
program would be run. But I guess it's an acceptable cost if we want to 
get people to run D-Bus by default.
