Short description of error
Limit rotation constraint with For Transform crashes when user selects Axis Angle rotation mode

Exact steps for others to reproduce the error
Give the default cube a Limit Rotation constraint
Activate "For Transform" box
Switch the rotation mode to "Axis Angle" in the Object panel or Properties shelf
Try rotating the cube
Crash

I have no crash with all other rotation modes however.
