Backtrace output on crash

I'm testing with Wine 1.5.1, Lubuntu 11.10 64-bit, Nvidia driver 295.20.

This bug applies to version 2.4.0 of the WinUAE Amiga emulator. WinUAE can use
either DirectDraw or Direct3D for its graphics output. I get a crash on
changing the graphics API from DirectDraw to Direct3D after starting the
emulation.

To reproduce the problem:
- Download and run the WinUAE installer. Run WinUAE.
- When the settings window appears, click Miscellaneous in the treeview. Note
that the default graphics API is DirectDraw.
- Click Start. The emulation window opens and after a few seconds the insert
media screen appears. There's a red mouse pointer which you can move.
- Press F12 to bring up the settings window. Click Miscellanous in the treeview
and change Graphics API to Direct3D.
- To work around Wine bug 10643, click in the emulation window then press and
release F12.
- Click OK to continue the emulation.
- WinUAE usually crashes at this point. If it doesn't, repeat the previous
three steps to change the graphics API again a few times.

In my testing, setting graphics API to Direct3D before starting the emulation,
starting emulation then changing API to DirectDraw, I don't get a crash. The
crash only seems to happen when switching from DirectDraw to Direct3D.

When it crashes, a dialog box appears with caption Crash, and text like this:
  Crash detected. MiniDump saved as:
  C:\Program Files\WinUAE\winuae_240_yyyymmdd_hhmmss.dmp
On clicking OK a Wine Program Error window appears. Backtrace output from that
is attached.
