I have update wxPython to 2.8.12.1 on Mac OS X Lion for Python.org 2.7.
Now I am seeing an assert that was not there on older versions of wxPython.
File "/Users/barry/wc/svn/pysvn/WorkBench/Source/wb_tree_panel.py", line 270, in initTree
self.tree_ctrl.EnsureVisible( first_item )
File "/usr/local/lib/wxPython-unicode-2.8.12.1/lib/python2.7/site-packages/wx-2.8-mac-unicode/wx/_controls.py", line 5530, in EnsureVisible
return _controls_.TreeCtrl_EnsureVisible(*args, **kwargs)
PyAssertionError: C++ assertion "m_heightText != -1" failed at /BUILD/wxPython-src-2.8.12.1/src/generic/treectlg.cpp(201) in GetTextHeight(): must call CalculateSize() first
Is this a bug in wxPython or do I have a new condition to check for before calling EnsureVisible?
The fragment of code leading up to this is:
if first_item:
self.tree_ctrl.SelectItem( first_item )
self.tree_ctrl.EnsureVisible( first_item )
What is the current state of the treectrl at that point? For example, has it been shown and painted at least once? I assume from the above that it has items, how many? Enough to need to be scrolled? If you can duplicate the problem in a small sample I can take a closer look at what is going on.

Never shown, one item, does not need scrolling.
