Alas runwine depends strongly on wine behaviour which change with time...
You need to check that your runwine is compatible with your wine.

You can check the exact test done in 
Omingw-i686/config.log which is something like
cd config
i686-w64-mingw32-gcc-posix -O3 -Wall -fno-strict-aliasing endian.c -o mingw-i686-endian11985
./mingw-i686-endian11985

The current version I use is below.
Another option is to use the package wine-binfmt, but I did not try it yet.
runwine purpose is just to deal with the minor difference in calling
conventions between linux and wine.

If you still have, issue write me privately and I send you my whole
setup.

Cheers,
Bill.
