Bug#702295: zenity: Zenity windows get TOO HIGH when text contains many words

[Thanatermesis]

Package: zenity
Version: 3.4.0-2
Severity: important

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA256

- --info , --warning , --error windows get higher for each word which is
added to
the text.
Seems like useless blank lines are added below the text.

This is a big usability issue for all the applications using Zenity, which
apt-cache rdepends can show a good number of them

HOW TO REPRODUCE:
zenity --info --text='A b c d e f g h i j k l m n o p q r s t u v w x y
z'
zenity --warning --text='A b c d e f g h i j k l m n o p q r s t u v w x
y z'
zenity --error --text='A b c d e f g h i j k l m n o p q r s t u v w x y
z'
zenity --error
- --text='A-b-c-d-e-f-g-h-i-j-k-l-m-n-o-p-q-r-s-t-u-v-w-x-y-z'

Examples which DON'T have the bug:
zenity --question --text='A b c d e f g h i j k l m n o p q r s t u v w
x y z'
zenity --error
- --text='A,b,c,d,e,f,g,h,i,j,k,l,m,n,o,p,q,r,s,t,u,v,w,x,y,z'

Note that this bug was already reported on ubuntu too, which still
exist on their version 3.6.0 of the package, I re-used some contents
of that report and the link to it is:
