Simple example code caused a crash

[jkdoug]

I replaced my main() code with the code from the "Basics" page, and playing around with the tree/list views, I managed to crash it. I am using the 1.4 release code, not the latest development branch. This is all the information I have to give on it:

Hi, thanks for the report. Would you please test it against the master? The tree views had a lot of internal changes since the v1.4 release which fixes quite a few things.

I was unsuccessful at building the latest revision, which is why I went with the 1.4 release.
