Export Dialog Give NullPointerException on OS X Snow Leopard

[Pugio]

Any attempt at exporting immediately throws a NullPointerException. This is triggered either by selecting any option from the "File > Export" menu, or pressing the "SVG" button in the Preview Settings window.

I was able to reproduce the bug, thanks for your feedback. I'll fix this.

[Mathieu Bastian (mathieu.bastian)]

I fixed this issue. I updated the module on our server, so you can profit from the fix immediately by updating your Gephi (Help > Check for updated).

[Pugio (pugiox)]

Thanks for the amazingly quick fix. I've noticed a bunch of other not quite
as critical bugs that I'll be sure to submit as well.

This bug remains:

"I was trying to export a SVG file from the preview and the attached error occur. I'm using a MacbookPro with SnowLeopard.
I've followed step by step the tutorial guide (it worked nice!), but I cannot export the image."
