Comment 1 for bug 1262709

OK I edited the title and description to better describe the issue which I eventually tracked down.

When a layout is renamed an "edited" signal is generated calling a function on_layout_name_edited. The first parameter passed to this function is the cell that was changed. The old value is taken from this cell, and that value is used to lookup the entry in config. The new name is passed as another parameter.

At least that is what is supposed to happen. For some reason every so often (10-20%) the wrong cell is passed. This is what causes the wrong layout to be renamed. What is really strange is that as well as the cell, a "path" is passed. The path is a sequence of numbers that point to the cell, yet the path is always correct even when the cell is wrong. I have implemented a workaround to handle this by using the path to look up the value from treeview.

This behaviour (as far as I can see) does not happen in the GTK3 port, so I'm thinking this is something in the gtk libraries that has been fixed (knowingly or not) in the interim.

Note that the Profile list uses the same code, and although I have not seen it, it probably occurs there too. I will check and implement the same fix if so.

Will update the ticket when the fix gets committed.
