I did have the same problem and was not find a solution too (actually I am not 
familiar with gtk).
But now I have tried to use GtkTable to edit tabled-data and it seems to works 
fine for me. It even tabs from one cell to another - without any changes.

Probably TreeViews are not really designed to be editable ...
