Yes, is done. The problem was, that the uwerr code directly accessed 
"interp->result" to obtain a string representation of the result of a 
Tcl-function. That is deprecated since at least 2003, and now with Tcl 8.5 
finally really doesn't work anymore. The correct way to obtain this string is 
to use Tcl_GetStringResult(interp).
