gEDA-user: Serious Bug in pcb-20060822

[Stefan Salewski <mail@xxxxxxxxxxxx>]

Hello,

I think there is a serious bug in pcb-20060822.
If a new layer (outline for board manufacturer) is added, 
thermals vanish or similar strange things occur.

The story:
 I started my first gEDA board design 10 weeks ago using gschem, 
gsch2pcb and pcb-20060822. At that time gsch2pcb gave me a 
starting board with 6 copper layers (no layers unused1 and 
unused2 as in older releases). After finishing my layout, I 
noticed that an additional layer for board outline in necessary, 
so i added a new layer with preferences menu. This step seems to 
be buggy. I got a layout with missing thermals. I have not 
noticed this error when sending the gerbers to the board 
fabricator, so now I have a board with missing connections to 
ground planes.

I think you can reproduce this bug if you use pcb-20060822 with a 
layout of your own and add an additional layer. Or you can 
download my gEDA layout from
http://www.ssalewski.de/AVR_USB_gEDA.html.de
and add a layer. There is currently no englisch version of this 
page, but you just have to scroll down and click on file
AVR_USB_gEDA-20061016.tar.gz (36k)
to download the archive. To use it, it may be necessary to insert 
in directory footprints a softlink to a directory which contains 
the footprints of John Luciani.

(The gerbers with missing thermals are still available at
http://www.ssalewski.de/boarddata.zip)

If you can verify this bug: How can I add an outline layer to my 
data without destroing the layout. I hope I will not have to do 
the whole layout again starting with 8 layers!

Best regards

Stefan Salewski
