Destination on inbound routes not saved

On the inbound routes section, when selecting a destination, the destination is not saved.
When looking at the httpd-error-log, I found that in core/functions.inc.php at line 488 the following was stated:

$destination=${$goto_indicate0.'0'};

But $goto_indicate0 isn't a variable! It should be defined in page.did.php, but this variable is called $goto. I changed in core/functions.inc.php the variable $goto_indicate0.'0' to $goto0.'0'.

After that, I can change the destination on the inbound routes again.
