I don't know if there is any simple solution. 
I ended up using the following work-around:

getVariables:=
  With[{stream=OpenTemporary[PageWidth->Infinity],oldurgent=$Urgent},
	$Urgent=stream;
	Information["`*"];
	Close[stream];
	$Urgent=oldurgent;
	ReadList[stream[[1]],String]
  ]

If your operating system doesn't remove temporary files automatically
you have to delete them explicitly before exiting the function.
