inkscape applet crashes when select spiral objet

[Lina Gaitán]

Inkscape 0.91 r13725 applet crashes after selecting a spiral objet.
Running in MAC OS Y Yosemite 10.10.5

The bug appears only in the file attached. The spiral was drawn and then some presets were modified ramdomly, trying to give it a better aspect. trying presets, the spiral was vanished and was imposible to select. then I draw another spiral and when the invisible one is selected or when the new one is selected the applet crashes.

File seems to work ok on Win 8.1-64, Inkscape 0.92.1 r15371.

running Windows 10, Inkscape 0.92.1 r15371 (32 bit)

I sometimes get the DOS warning message:
sp_gradient_fork_private_if_necessary: Orphaned gradient

when I drag the spiral. However, no crash, and the drag appears to work properly.

Triggered in Fill&Stroke dialog due to broken gradient reference (missing gradient definition, referenced with xlink:href="#linearGradient9058" in gradient id="radialGradient9064", which is applied to stroke of spiral with id="path6074"), fixed in rev 14324:
https://bazaar.launchpad.net/~inkscape.dev/inkscape/trunk/revision/14324
as confirmed with local archived trunk builds (r14322 not ok, r14325 ok). The fix is included in Inkscape >= 0.92.

Modified version of the SVG file attached with broken stroke gradient replaced by solid stroke color - just in case the reporter needs to continue working with that document: the modified version allows editing without risking the same crash again while using the affected latest official build available for OS X (0.91 r13725).
