segfault crash

[JMLX42]

I'm using your addon on ubuntu 14.04 64bits with Blender 2.75
When I press either the prepare or bake button, Blender crashes because of a segfault.
The stack trace is below.

FYI I've logged the bug in Blender's bug tracker here: https://developer.blender.org/T45492
It would still be nice to have a workaround though...

Sorry, i'm terribly busy these days. but i'll try to check it ASAP.
By the way i'm using blender 2.74 + easy_lightmap on manjaro linux just fine.
