barh_demo turns the grid on. I accidentally set the default linestyle to '-' 
in mplconfig for the grids, thats been fixed.

It looks like creating the mplConfig object is adding to the startup time. 
I'll look into it when I get a chance.

Darren,
There is *major* speed problem. Running "backend_driver.py Template":
0.95 minutes with NEWCONFIG = True
0.51 minutes False

Darren,
It looks like there is a problem with the grid lines. Although the 
matplotlib.conf file is specifying linestyle = ':', and False for the 
axes.grid parameter, everything is coming up with solid lines (see 
barh_demo.py, for example) by default. It looks like those two keys are 
not setting their respective rcParams entries.
Eric

Darren,
When I make a clean build and install, set NEWCONFIG, and try to run I 
get a permission problem. It looks like the problem is that the global 
matplotlib.conf is not getting generated and installed at build/install 
time, but I have not investigated it.
Eric
convert!

That was exactly the problem, I forgot to add the new file to the setup 
script. It is fixed in svn 3640.

Should be fixed now. The bug was only exercised when 
svg.embed_char_paths was turned off.

I think I broke that for a few hours this morning, but it's working for 
me now. Next time you update, please let me know if it still isn't 
working for you.
