Short description of error
Adding a new Curve->Bezier object and then immediately assigned an Array modifier to it will crash.

Exact steps for others to reproduce the error
Please start with the default .blend -- loading an existing file doesn't seem to trigger the issue.

Load default scene
Add a new Curve -> Bezier
Add an Array modifier to that new curve
Crash

Exception thrown: read access violation.
