--- Comment #3 from Vincent Povirk madewokherd@gmail.com --- If you have dbghelp.dll disabled for Hearthstone, and it tries to embed IE in its process, then that won't work (as you've observed, it requires dbghelp). But the real bug that needs to be fixed is the requirement that dbghelp be disabled (bug 33947).
I don't think there's likely a connection to bug 35291. I'm not very familiar with this issue, and bug 33947 is unfortunately a bit hard to follow, but it seems to imply that one can work around the bug by applying a patch instead of disabling dbghelp. If the patch also works around bug 35291, then what you've seen could be relevant there. Either way, it would be useful to have that information on bug 35291.
And in either case, this bug is invalid. It's expected that disabling dll's can break builtin Wine components, and the strange part is that disabling dbghelp somehow makes Hearthstone work better.
