Title:
  zenity window too big, not even proportional to text length

Status in “zenity” package in Ubuntu:
  New

Bug description:
  * Context

  Simple execution of zenity

  * Summary

  zenity window opens too big. 
  The text appears on top but most of the window area is just empty.

  * How to reproduce

  Just type this :

  zenity --info --text="$( for (( A=0; $A<20; A=$A+1 )) ; do echo -n
  'lorem ipsum ' ; done )"

  * expected

  Window fits text

  * observed

  Window much too big. More than 90% window area is blank space.

  * Additional information

  It's not just a matter of too long a line. If text is cut in short lines, 
window is still too big (though proportionally it seems).
  Notice below "echo -n" replaced with "echo".

  zenity --info --text="$( for (( A=0; $A<20; A=$A+1 )) ; do echo 'lorem
  ipsum ' ; done )"

  
  Trying with different text length shows that window area is not proportional 
to text length but grows much more rapidly.
  In other words, the longer the text, the higher the percentage of wasted 
space.

  This command shows a sequence of 30 zenity windows with increasing
  text length each time you press enter. You can see the trend easily.

  for (( LENGTH=0; $LENGTH<30; LENGTH=$LENGTH+1 )) ; do echo $LENGTH ;
  zenity --info --text="$( for (( A=0; $A<$LENGTH; A=$A+1 )) ; do echo
  -n 'lorem ipsum ' ; done )" ; done
