Bug ID: 39667
           Summary: dinput: MotoGP 3 demo launcher crashes on leaving key
                    configuration dialog.
           Product: Wine
           Version: 1.8-rc1

          Severity: normal
          Priority: P2

Created attachment 52886

motogp3-demo-launcher-crash.txt with wine-1.8-rc1

Probably same issue as in https://bugs.winehq.org/show_bug.cgi?id=12432 .
(Attached backtrace seems equal.)

Steps to reproduce:
- start launcher
- "Configure Controller"
- leave dialog with "Cancel"
- crash

MotoGP 3 demo launcher uses ConfigureDevices for the key mapping.
This seems because the result of a GetProperty(DIPROP_USERNAME) is used
without checking.
