"Extra TeX fonts not found: jsMath-cmmib10" even though ttf-jsmath (including jsMath-cmmib10.ttf) is correctly installed

[Iacopo Meladoro]

Binary package hint: ttf-jsmath

# What happened:
After installing ttf-jsmath (0.090709+0-1), pages featuring jsMath TrueType fonts fail to recognize and use the jsMath-cmmib10 font even though it is correctly installed via the ttf-jsmath package.

This has been tested on both Firefox 4.0.1 and Chromium 11.0.696.71 (86024). It is reproducible always.

In Firefox 4.0.1, a jsMath error message is displayed, quoted here in full:

"Extra TeX fonts not found: jsMath-cmmib10
Using image fonts instead. This may be slow and might not print well.
Use the jsMath control panel to get additional information."

In Chromium 11.0.696.71 (86024) no jsMath error message is displayed but, as in Firefox, math using the jsMath-cmmib10 font is rendered using images while everything else is properly displayed using the TrueType fonts.

Before installing the package, the same page displayed the same kind of error message in Firefox, but referencing many jsMath fonts rather than just jsMath-cmmib10. Installing the package made the error go away for all fonts except for jsMath-cmmib10, even though the relevant .ttf file is contained in the ttf-jsmath package and gets installed properly along with every other font.

# What should happen instead of the above:
No error message, and correct rendering as TrueType of all jsMath notation, including the jsMath-cmmib10 font.

# Troubleshooting attempts:
I have tried replacing jsMath-cmmib10 with the version located at http://www.math.union.edu/~dpvc/jsMath/download/extra-fonts/welcome.html: no results. The behavior listed in this bug report remains unchanged.
