Docking manager crashes if you perform the following sequence of actions (demonstrated using the included sample "Simple Code"):

1. Close the floating form by clicking on the X

2. Select the right tab of the two panels that are docked together

3. Attempt to drag it off (to undock it) into the center area of the application

Call stack is visible in attached image. Using debug build shows that line 3156 of FBProvider.cs calls GetDockHostController and it returns null. dhc is then dereferenced on the next line without checking for null.
