can't save in eps

Hi,

I have an error with the SVN version of matplotlib when I'm trying to save a figure in eps format (it's working fine for png, svg). The problem appeared when I'm using savefig("image.eps") or the save icon.
The error message is:

Thanks,

Nevermind, I didnt see the reference to simple plot. This looks like a problem
with the where() function with numarray, it is complaining about creating a
char array. I'm looking into it.

Fixed in svn 2190.

I found a non-numerix solution, replacing this:
codes = where(mask[start:end+1], 'l', 'm')
with this:
codes = [('m','l')[i] for i in mask]
