Please describe the problem:
With some special strings set as commment the About dialog does not show them
correctly.

The string 
"AisleRiot provides a rule-based solitaire card engine that allows many
different games to be played."
has 2 problems. 

1) The string gets wrapped, but it looks as if the dialog box is not resized, so
some of the text is not shown in the right side. Altering the text a bit will
make the dialog box wider and all text is shown.
If the text is selected and copied and pasted elsewhere the text missing from
the right side is still there.

2) for some reason the . is no longer present at the end of the string. Other
strings with an . at the end has it shown. And replacing it with e.g. a comma
the comma will be shown.

I have tried a few different combinations of text to find a pattern but not
really succeded.

The string is a bit special because of the many i's in it. 



Steps to reproduce:
gtk_show_about_dialog (GTK_WINDOW (app),
			 "comments", _("AisleRiot provides a rule-based solitaire card engine that
allows many different games to be played."), NULL);



Actual results:
Some of the text i not shown on the right side.
The . is removed from the text.

Expected results:
Dialog box is expanded horizontally to fit the text inside.
The . should still be there at the end of the text.

Does this happen every time?
yes
