I can't reproduce the issue on Linux, so could be something platform dependent.

Does it happen with the default cube scene?

Something strange happens here. The Collada exporter attempts to convert the filename into a "native filename". I am not sure what exactly this is. In any case this conversion fails and an invalid UTF8 character string is created.

During my tests i could not reproduce the blender crash, but after export i found 2 files:

Modélisation.dae (was created with size 0 to test if the file can be created)
Mode´lisation.dae (contains the exported collada data)

The problem is that the special character é is converted wrong deep inside the OpenCollada code.
Now there are 2 solutions:

1.) Fix OpenCollada and replace the library with the fixed version.
2.) Write the collada data to a temporary file, then rename this file to the final filename after Collada has done its task.

How shall i proceed with this?
