winecfg hangs

Since a couple of day, launching previously working 64bit WINEPREFIX will get
stuck to the "The wine configuration in XXX is being updated, please wait"
I let it run for over a hour, even when creating completely new WINEPREFIX.  
It looks like by specifying WINEARCH=win32 all works fine.

As attachment the log when tryng to open winecfg on a non-existing WINEPREFIX.
Note ctrl+c is requested after a while, but despite some output being created
the process is still running.
