Looks like a missing glyph problem (in conjuction with one of the typical issues
of weird fonts). Since there is no fonts with a glyph, it is transliterated from
transliterate.properties as:
# U+1E49 LATIN SMALL LETTER N WITH LINE BELOW
entity.7753=n_
On Windows, I am seeing "cn_c", so what you see on Linux seems due to the fact
that the glyph picked for underscore is different (but not specific to MathML).

It works fine if I use HTML.

Maybe the MathML glyph measuring code is measuring enough space for "n_" and
when the two get renderered on top of each other it doesn't take that into account?
That might be the case. Perhaps the code is taking the delta that you see as the
italic correction. There is a subtlety with respect to this, e.g., try:
<math xmlns="&mathml;">
<mrow>
<mi>f</mi> <mo>q</mo> <mi>f</mi> <mo>I</mo>
</mrow>
</math>
vs.
<html>
<span><i>f</i> q <i>f</i> I</span>
</html>
There is a difference (Err, a significant difference for picky math author).
But I am not sure if that's where the difference with "n_" arises. I haven't
investigated yet. I will first need to grab a font with that glyph.

No bug for me, even when clearing font.mathfont-family in about:config. Tested on a linux trunk build.
