Q1) When importing geometries from Blender is ReadBlend a better option than Collada?

When I try to import the .dae file using the AppColladaDemo the program segfaults, with the following gdb trace(see below). The problem is caused by URI so I collected a list of id elements from the file (lines are truncated, see below).
I tried to attach the .dae file extension was not allowed.

Q2) What is this URI error caused by?

Q3) I only need the geometric data in Bullet, if it helps the URI issue is there a way to specify this to the Collada importer?

Q4) This question is somewhat unrelated to my problem but is openCollada currently the best Collada SDK?
