matplotlib-devel Mailing List for matplotlib

  Hi,

  Recently I asked to become  comaintainer of matplotlib in Fedora and
did update to 1.2.0
for the upcoming f18 and rawhide.

  I am also working on an experimental sagemath package that I hope to
get in f19 and
make a backport to f18. One example of the font problem is:

  I opened two bug reports about it at:
https://bugzilla.redhat.com/show_bug.cgi?id=885307 and
https://bugzilla.redhat.com/show_bug.cgi?id=885312

It "works", that is, is silent in f17, but it should be because f17
has stix fonts
1.0.0 and f18+ has stix-fonts 1.1.0. I am not sure how to correct it, so, an
experimental hack patch "to make it silent" is:

but this absolutely does not look right and proper to add to the f18+ matplotlib
package.

Any suggestion on how to properly correct it is welcome.

Thanks,
