Exporter exception

I'm getting this exception on a blend file:

I'm using Blender 2.48 with the exporter from SIO2_SDK_v1.2.1_REVISION_A.zip.

Apparently there's problem with a material. How can I find out what's going on? Unfortunately I cannot provide this blend file this time :-(

Best,

Got it. There were some indexes on some objects which linked to "empty" materials. I had to delete them for all objects manually and then it went smooth.

Although it seems that the Blender scene is somehow faulty then, I think the exporter should gracefully ignore this and continue...

Best,
Matt

I agree but, I never meet this situation... can you please reproduce the bug and send me a .blend so I can permanently fix it in the exporter.

Tks!
