Remote desktop crash

Hello,

when a developer went back to his computer after having launched one application from remote, the following crash occured:

The ribbon seems to be directly causing the crash. 

EDIT: After trials of several scenarios, we were able to narrow it down to the smallest number of steps:

SCENARIO-1

1. From PC#2, in Remote Desktop, start the application and click on the Back button in the backstage.
2. Disconnect the remote session.
3. Log-in on PC#1.

RESULT: The focus goes to a tab in the backstage. 

SCENARIO-2

1. From PC#2, in Remote Desktop, start the application and click on the Back button in the backstage.
2. Minimize the application window.
3. Disconnect the remote session.
4. Log-in on PC#1.
5. Restore the application window from minimized state.
6. Minimize the application window.
7. From PC#2, in Remote Desktop, restore the application from minimized state.

RESULT: The program has crashed and shows the error in the images above. Note that the ribbon is in an unnatural state.

Note that the problem occured on both Windows 8 and 10.
