Subject:	[geda-user] PCB autorouter doesn't create vias. Bug or user error ?

Hello everybody,

I am designing a really simple board and I cannot make the autorouter
work properly, and I'm not sure this is a bug or some error on my part.

I've uploaded my project here:
	http://popies.net/tmp/test.pcb

It is a simple 2 layer board, and I made a ground plane (using a
rectangle + thermals) on the solder side.

The autorouter is not able to route all the rats on the component
side, so it should make some vias and route the few remaining rats
on the solder side (by clearing through the ground rectable). But
it does not. (and yes, both layers and vias are visible).

I am using PCB 20140316 on Ubuntu 14.10.

Two remarks:
- I have used a few years ago an older PCB version (20110918),
and I didn't have this problem.

- The toporouter on my test project ( invoked using :toporouter() )
works as intended: it does create the vias. The result is not perfect
(some traces are too close to the thermals for example), but at
least it does not exhibit the same problem as the standard autorouter.

Am I doing something wrong or is the autorouter unusable (strangely
I cannot find any bug concerning this, and since it has been almost
one year this PCB version was released, I find this hard to believe...)

Thanks!
