brown paper bag fix

[Andreas Mohr <andi@rhlx01.fht-esslingen.de>]

Hi all,

I guess it's my turn this time ;-\

My App Path code didn't 0 initialize two HKEYs.
As that code is using "goto", the compiler was unable to figure out
that the HKEYs weren't properly initialized, so it didn't generate a
compile warning for me to notice it before I submitted that patch :-\
As the HKEYs weren't initialized, they were non-0 and thus being closed
on function returned.

This problem caused the winedos "invalid exe file" message, BTW.

How did it happen ?

Well, the stack at the HKEY place for some reason contained exactly the
0x20 value that the HFILE handle of the DOS binary used...
And as the code was doing a CloseHandle on that uninitialized registry
key...
...it closed the HFILE of the DOS binary !!
Thus the file seek and ReadFile failed -> "invalid binary".

In other words: dark brown paper bag :-)

Thanks God I became quite suspicious about the frequent wineserver log
errors, so I noticed the grave problem.

God knows in how many other cases this wreaked havoc...

Sounds like using "goto" isn't such a good idea after all...
Alexandre, please tell me if you even want me to rewrite the code not
using goto...

*sigh*
