set attributes to rows in GtkTreeView

[Bernd Demian <bdemian csc-dd de>]

Hi all,
thanks for the gtk-version, great job

btw I have one question, one bug and one suspicion.

First the question: Can somebody show me a simple way to change the
color of one or more rows in GtkTreeView. In CList it was simple to use
the function gtk_clist_set_background. 

Second the bug : I have gtk+ installed on True64 and in the testgtk appl
it crased when I select the text.
Here is the stack from core file. I hope somebody can find the bug.

and thirdly the suspicion, when you compress a string with g_strcompress
and the last char is '\', it seems the function destroyed the memory.
