Summary: Project layers do not render until I load a layer manually

Initial Comment:
They're in the list; they just don't render until I load another layer.  Then 
the project layers appear, plus the one loaded manually.  The manual layer may 
then be removed.

Using version 2.4.0, installed today from the repository, on Ubuntu 10.10

Thanks Aaron,
   I'm not able to fully replicate the bug, but I think I see the problem.
 On my machine, if one of the empty layers is visible, then the zoom to fit
button doesn't fully center everything (it's slightly off).  Looking at the
code, the empty layer is messing up the bounding box calcs.  I've fixed the
in git now.  If you feel inclined to check it out and compile it, please
let me know if it does not fix the problem.  I'm guessing it should fix
this.
  And the RS274D message happens when there is nothing in the layer, since
gerbv can't find enough data to confirm it's a RS274X file...don't worry
about the message.

Cheers!
Julian

Oh, one more thing - opening a blank layer produces this error message,
even though my CAD software uses the same settings for all of them:

Most likely found a RS-274D file...trying to open anyways

Yes, the Best Fit button does it too:
1. Load a project file, either from the command line or the GUI
2. Layer list is correct, including order, color, and inversion, but the
display is blank
3. Open another layer manually
4. The display now shows all layers correctly
5. Resize the window and click the Best Fit button
6. GOTO 2

I noticed just now that I can cause the same problem just by opening a
blank layer manually.  (view.GTP and view.GBP are blank)  The bottom layer
in this project file is view.GBP, so I opened the project file in a text
editor and took it out.  Then the problem went away.

I opened the blank bottom layer manually, and I was back where I started. 
So I guess the real bug is that simply having a blank bottom layer prevents
any layers from showing...at least on my machine.

Thanks!

Message:
Hello,
  Could you explain the problem a bit more?  If you click on "open
project", then choose the view.gbp file, does nothing appear?  If nothing
appears, does the "Best Fit" view option render the files?
  Your test files seem to work completely fine on my machine.

Cheers--
