I have used a qtreeview and when i click in the + at the second level it fills the model and when it tries to show the tree it crash
Qt Code: 
  1. - level 1
  2.     + level 2
To copy to clipboard, switch view to plain text mode 

It gives to me this error ? Anyone knows the cause?
ASSERT: "i > -1" in file itemviews/qtreeview.cpp, line 3130

Sorry for my english
