Hi,
I cleaned the patch, it is much smaller now.

Should we make dissector_add() and friends fail silently when the
referenced dissector is not available? Currently the g_assert() is
killing, while a return would suffice.
This becomes more relevant since we can delete a dissector on the fly,
so we may run into this assert while not expected.
By the way Jean-Grégoire, could you clean up the patch on the Wiki a
bit? There seems to be residual development stuff in there, which may
cause conflicts.
Thanx,
Jaap
