Error/Sefault for loading vertex data (devel branch) with multiple objects

#Attempt to load vertex data

Things that happen

• segault (sometimes)
• get_colour_code(): invalid piecewise function. spams the console (sometimes) and the colour of the object is black
• just works as normal (sometimes)
• Loads as black, on exit reports: *** Error in `Display': munmap_chunk(): invalid pointer: 0x0000000002da3098 ***

This is all for the same objects and vertex files.

So, I'm guessing memory corruption problem, probably a bad pointer and the failure depends on the content of the memory?

@gdevenyi Should be fixed.
