Log of Firefox Nightly startup

Trying to run a Firefox debug build (you may take the latest Nightly for
testing purposes found on:
https://ftp.mozilla.org/pub/mozilla.org/firefox/nightly/) under wine (1.5.28
and 1.4) leads to an infinite loop containing

### ERROR: WalkStack64: Invalid handle.

(see attachment for a bit more output).

This happens both on 32bit and 64bit systems (I used an Ubuntu 12.04) with the
32bit Firefox version (64bit Windows versions are not supposed to work).
Non-debug versions of Firefox are working fine with Wine. And nightlies are
working fine on Windows.
