This is a GStreamer bug; the plugin is hanging in its registration function.
Are you entirely sure? How exactly anything hanging could lead to the "could not load kernel32.dll" error message? Why would winecfg load gstreamer in the first place? (And as far FreeBSD's Wine is concerned, it's typically built without gstreamer support.)
Now, it's almost certain there is some kind of mixup, but in my opinion the actual bug report message should take priority over everything else.
