Same issue as in missing stix reported in #885307 but in this case the fonts are not in the source rpm. Link to download directory is http://www.math.union.edu/~dpvc/jsmath/download/extra-fonts/ And reason is some missing fonts, that are required by python-matplotlib: $ egrep -i "'cm" /usr/lib64/python2.7/site-packages/matplotlib/mathtext.py if cached_font.font.postscript_name == 'Cmex10': _fontmap = { 'cal' : 'cmsy10', 'rm' : 'cmr10', 'tt' : 'cmtt10', 'it' : 'cmmi10', 'bf' : 'cmb10', 'sf' : 'cmss10', 'ex' : 'cmex10' prop = FontProperties('cmex10') 'cm' : BakomaFonts, "mathtext.fontset must be either 'cm', 'stix', " and cause some failures, for example in my sagemath package: doctest:1214: UserWarning: findfont: Font family ['cmb10'] not found. Falling back to Bitstream Vera Sans doctest:1214: UserWarning: findfont: Font family ['cmtt10'] not found. Falling back to Bitstream Vera Sans doctest:1214: UserWarning: findfont: Font family ['cmss10'] not found. Falling back to Bitstream Vera Sans I believe these fonts could be added in a jsmath-fonts-extras but I believe python-maptlotlib could also be patched to not require those (and the extra stix-fonts").
I think I found an workaround that will cause it to not require fonts not in the common js-math linux fonts tarball. Since the stix-fonts bug report was closed as NOTABUG, this one should also be so, as it is a smaller problem, and the workaround should no longer trigger the warning messages.
Sorry for not replying yet, been a bit busy. :-/ Fwiw, I'm open to adding those (to an -extras subpkg perhaps) if there is still any remote need for these.
python-matplotlib-1.2.0-7.fc18 has been submitted as an update for Fedora 18. https://admin.fedoraproject.org/updates/python-matplotlib-1.2.0-7.fc18

They should no longer be required. Well, they "could" be used if available, but now it no longer generates any warning. I am also hoping to find some time to split more the python-matplotlib package, and add missing packages required to make extra backends functional, as well as test the ones that have all requires already in fedora and add they to requires and build requires as applicable.
