[Reportbug-maint] Bug#607175: Report bug crashes with floating point error

[Paul Sohier]

Package: reportbug
Version: 4.12.6

reportbug crashes with a floating point error when using the GTK and 
after filling in the package name in the GTK:

/usr/lib/pymodules/python2.6/reportbug/ui/gtk2_ui.py:476: PangoWarning: 
pango_layout_set_width: assertion `layout != NULL' failed
   gtk.main ()
/usr/lib/pymodules/python2.6/reportbug/ui/gtk2_ui.py:476: PangoWarning: 
pango_layout_get_extents: assertion `layout != NULL' failed
   gtk.main ()
/usr/lib/pymodules/python2.6/reportbug/ui/gtk2_ui.py:476: PangoWarning: 
pango_layout_get_line_count: assertion `layout != NULL' failed
   gtk.main ()
Drijvende-komma-berekeningsfout

This only happens when the --configure option was tried before, and not 
finished.
