wine-1.7.47-118-ga90592c console output

Expanding then collapsing the top arb row with the +/- button results in an
error, but only if it is the top row. Other rows open and close without
incident.

1. "winetricks -q dotnet40" (Bug 37883)
2. Install, run, log-in. (Login required)
3. Expand the top arb details with the + button.
4. Collapse the top arb details with - button.
5. Error: "We're very sorry but a serious error have occured." [sic]

Nothing new is printed in the console.

Native gdiplus makes no difference.
