Collada export fails

Hello!
With blender 2.47, the collada importer/export don’t work corectly. Example: I can import the jenga.dae that comes with the bullet-sdk, but I can’t import an scene cretaed with this same blender:S.

this is the error trace:
FEEDBACK: Illusoft Collada 1.4 Plugin v0.3.159 started
