Crash when defragmenting

I only start (drive C: is choosed) and press Defragment. After few second crash window appear.

Can you fix it? What information will be useful for determine errors?

good, we want it to that way the crash can be seen :)

The developers read all crash reports so this is a good start

They may ask for more information but they also may not... but have heart for they will see it:)
