Like Kornél said you're depending on a specific behavior than neither GDI+ nor
(MS) System.Drawing.dll guarantees (i.e. you're *lucky* it works on Windows and
it could break, without being a "bug", with any update).

I'm lowering the severity because even if we can shorten (or remove) the window
where this crash can occur (the one in GdipDeleteGraphics), you'll hit another
one soon afterward (believe me I tried ;-).

Neither SD, libgdiplus nor cairo is built to handle this. The "real" best
solution would be to throw in the current thread != original thread (but that
would not solve your issue).
