bug#4910: 23.1.50; Error while displaying tooltip

[Juri Linkov]

Some recent changes broke tooltip display on non-toolkit X builds.

Hovering the mouse over a menu item or a toolbar icon results in the
error message:

  Error while displaying tooltip: (error Invalid frame name--not a string or 
nil)

and after a delay the tooltip is displayed in the echo area instead of the
tooltip frame.
