crash when opening SVG font file

[1024]

Have to avoid any way.

may be..., detect it before crash causes, and display an alert message.

OR

cf. SVG font can't drop on Safari. So, it might mean that there is a way to determine it using identifier or something.

Ups, it was only because the SVG font file was gzipped. Unzipped SVG font files can be drop and open on Safari, though Safari doesn't crush.

I don't know what was wrong, and what resolved this. However anyway, this doesn't occur anymore, when I've tried this again.
