This version is fairly old; please try with 3.0.2.

I can reproduce this with master branch, windows 8.1 and miktex 2.9.6630.
It bisects to #11381

Looks like a duplicate of #10272 (try installing the cm-super tex package)?
(It may make sense to switch from computer modern to latin modern at some point, which at least has the advantage that we can check for its existence with \usepackage{lmodern}.)

Installing cm-super solves this for pdf output, but not for svg. In the svg case I get
And the output is a svg file without the
°symbols.I think the main point here, in contrast to #10272 is, that a standard empty plot should not fail for standard latex installations.

Looks like if you zoom a lot, you'll see a tiny degree sign, which suggests to me that the problem is the same as the one described in #12928?

Yes, with current master, the warning reads

The warning is actually spurious (per #14156), but the sizing problem is real.
