Backtrace of crash

To reproduce (in GNOME, at least):

* Run clipview (from http://bugs.winehq.org/attachment.cgi?id=25952), mspaint
or probably any program that can paste the CF_BITMAP clipboard format.
* Press the Print Screen key.
[gnome-screenshot ("Save Screenshot") should appear.]
* Click Copy to Clipboard.
[clipview won't refresh automatically. That is bug 19418.]
* Press F5 in clipview to refresh (or paste, in mspaint, etc).
[The screenshot should appear.]
* Close gnome-screenshot.
* Press F5 again (or paste the CF_DIB format).
[An error will occur in clipview - can't read CF_DIB for some reason.]
* Select View -> 0x0002: Bitmap Image in clipview (or paste the CF_BITMAP
format).
[Crash.]

Backtrace attached.
On wine-1.1.37-230-g3ed5df1 + my clipview patch.
In a clean prefix.
