I also tried to reproduce the problem in an isolated configuration with
version 1.0.13, but

at the moment I cannot reproduce the failing configuration anymore ...
(not with 1.0.13 nor with 1.0.24 ...)

As I remember the following may happened:
- - I changed the configuration using /8 subnet in the host configuration
- - I reloaded tinc through kill -HUP or /etc/init.d/tinc reload
  (which seems to not enough for such a change)
- - I changed the configuration using two /9 subnets
- - now I restarted tinc - and it worked

Now it works with /8-subnet too.

A subnet change in the host configuration file needs restart of tinc,
not only a reload.
That was the real source of my problem.

(this is reproducable: change/remove a subnet line, do kill -HUP,
nothing changes in the subnet list)
