Crash when parsing invalid SVG containing "inf" attribute

[Nicholas Fraser]

Inkscape crashes when trying to open an SVG file containing the following:

<svg width="1280.0" height="640.0">
<line x1="642.4697456162015" y1="+inf.0" x2="637.5302543837985" y2="-inf.0" style="stroke:rgb(255,0,0);" />
</svg>

This is obviously invalid SVG, but Inkscape should complain about it being corrupt rather than crashing.

Inkscape 0.91 r13725 (Oct 2 2015)

On OS X 10.7.5:
- crash not reproduced with Inkscape 0.48.5 r10040
- crash reproduced with Inkscape 0.91 r13725, 0.91+devel r14452

Backtrace with debug build (r14434)

Also reproduced on Xubuntu 15.10, Inkscape trunk rev. 14504.
Checking attributes in the SVG output preferences doesn't help.

Inkscape still crashes on Windows XP (32-bit), Inkscape 14648 (after the 2geom update rev. 14639, see http://bazaar.launchpad.net/~inkscape.dev/inkscape/trunk/revision/14639).

I believe this is fixed by https://gitlab.com/inkscape/inkscape/commit/8e05bcd2bbdd0536a91b1c01d1947437c7f0144e, which has been released in 0.92.4.
