[Bug 24324] Firefox 4.0 Beta 5 sometimes doesn't allow toolbar customization on tmpfs

I just noticed something else strange going on here aside from drive type
detection. This is what I just did:

mkdir ~/.wine
sudo mount -t tmpfs tmpfs /home/me/.wine -o uid=1000
~/wine-git/wine "Firefox Setup 4.0 Beta 5.exe" <- works
rm -rf ~/.wine/*
~/wine-git/wine "Firefox Setup 4.0 Beta 5.exe" <- creates a broken prefix and
doesn't allow toolbar customization

The broken prefix only contains the following files (until I install something,
anyway):
./system.reg and user.reg
./dosdevices/c: and z:
./drive_c/windows/win.ini
./drive_c/windows/system32 <- empty folder

Does this procedure look correct to you, or am I doing something here to break
the second wineprefix creation?
