Crash log for Speedy Blupi demo near Wine 1.3.34

Several games by Epsitec which feature their Blupi character don't render
correctly if run after "winetricks ddr=gdi". This is a regression.

The games with this problem are Blupi at Home, Speedy Blupi and Planet
Blupi. Demos can be downloaded from http://www.ceebot.com/blupi/load-e.php

I tested Speedy Blupi, http://www.ceebot.com/download/blupi/speedy-e.exe

With the default opengl renderer the game works correctly. However after
"winetricks ddr=gdi", with or without virtual desktop mode the game just shows
a blank/black screen. The program is running, it just doesn't display anything.
(You can click to quit if you know where to click.)

I did a regression test, but unfortunately the result wasn't conclusive.

 1.3.33 GOOD
 1.3.34 get a crash on running the program
 1.3.35 BAD, black screen

I bisected between 1.3.33 and 1.3.34 to find which commit caused the crash:

0f10ac93580d5a055f0b3f6e7c3d77738135f031 is the first bad commit

ab3f595c09537f3f18bd03bbe708c584f62e3952 M    dlls

I then bisected again between there and 1.3.35 (doing git bisect bad on black
screen/no crash), which gave this result:

c43aa1ada82e30168a373d584ad7ef62a5e04677 is the first bad commit
commit c43aa1ada82e30168a373d584ad7ef62a5e04677

(Presumably commit c43aa1ada82e30168a373d584ad7ef62a5e04677 *isn't* bad, git
just said that because I had to reverse conditions for the second bisecting.)

I've attached console output when the program crashed, but that probably isn't
too relevant since it doesn't crash any more.

I guess the next step would be bisecting between commits
0f10ac93580d5a055f0b3f6e7c3d77738135f031 and
c43aa1ada82e30168a373d584ad7ef62a5e04677, but at each step reverting commit
0f10ac93580d5a055f0b3f6e7c3d77738135f031???
