           Summary: kate crashes if Python highlighting is used
           Product: kate
           Version: 2.2.1
          Platform: unspecified
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kwrite-devel kde org
        ReportedBy: hk_classes knoda org


Version:           2.2.1 (using KDE 3.2.2, compiled sources)

If you copy the following script in Kate and then switch to Python highlighting, Kate \
-and other apps that use the kate part - crashes.


mymakro(hk_this,"das Makro!")

redcolour =hk_colour(255,0,0)
greencolour =hk_colour(0,255,0)
form=cast_form(hk_this.presentation())
label=form.get_visible("NeuesFeld_5")
if hk_this.foregroundcolour().red()!=255:
	hk_this.set_foregroundcolour(redcolour)
	hk_this.set_backgroundcolour(greencolour)
	hk_this.set_label("grÃŒner Knopf")
	label.set_backgroundcolour(greencolour)
else:
	hk_this.set_foregroundcolour(greencolour)
	hk_this.set_backgroundcolour(redcolour)
	hk_this.set_label("roter Knopf")
	label.set_backgroundcolour(redcolour)

hk_this.set_position(hk_this.x()+50,hk_this.y()+10)
parent =cast_form(hk_this.presentation())
parent.get_visible("NeuesFeld_2")
