Treeview problems / gtk app crashes when collapsing an iter

["Tuxboy" <tuxboy web de>]

My problem:

I created a treeview widget with some main nodes. The application crashes when I collapse an iter and a child iter is selecetd.

 

 

e.g.:

 

+ Iter 1

+ Iter 2

-  Iter 3

    + Iter 3.1

    + Iter 3.2    <---- selected

       Iter 3.3

+ Iter 4

[...]

 

I selected "Iter 3.2" and want to collapse "Iter 3" -> Crash.

Can somebody tell me me how to avoid this ugly crash??

 

Best regards,

Robert.
