New issue 354 by uAle... at ...626...: TreeView.RowToItem.296: #13: Null  
object (gambas3 r5302)
http://code.google.com/p/gambas/issues/detail?id=354

1) Describe the problem.

Using the "listview" data-type sometimes causes "Null object" when clicking  
on a "blank" area.
_TreeView.RowToItem.296: #13: Null object
1: _TreeView.RowToItem.296
2: _TreeView.UpdateRowHeight.1275
3: _TreeView._UpdateItemHeight.1289
4: _TreeView.SortItem.587
5: _TreeView.Sort_Timer.1128

This worked fine on gambas 2.24.0

2) GIVE THE FOLLOWING INFORMATIONS (if they are appropriate):

Version: TRUNK
Revision: r5302
Operating system: Linux
Distribution: Ubuntu 10.04
Architecture: x86
GUI component: QT4
Desktop used: LXDE

3) Provide a little project that reproduces the bug or the crash.
Project is attached.

4) If your project needs a database, try to provide it, or part of it.

5) Explain clearly how to reproduce the bug or the crash.
Open the application and click on the left list on the items and then click  
in the view on the empty area (repeat it a few times if first time doesn't  
work)

6) By doing that carefully, you have done 50% of the bug fix job!

IMPORTANT NOTE: if you encounter several different problems or bugs, (for
example, a bug in your project, and an interpreter crash while debugging
it), please create distinct issues!
