asserts "traits" failed in wxStandPathsBase::Get()

wxPython,

Using wxPython 2.9.4.0, the editor I use is reporting the following wxWidgets debug alert message:

  ..\..\src\common\stdpbase.cpp(49): asserts "traits"  failed in
   wxStandPathsBase::Get() create wxApp before calling this

The editor I use is the tabbedCodeEditor from Pythoncard.
The tabbedCodeEditor works using wxpython.2.8.12.0

I narrowed the error message to the following statement in the file STCStyleEditor.py:

cfg = wx.FileConfig(localFilename=configFile, style=wx.CONFIG_USE_LOCAL_FILE)

The above statement is called many times but the debug alert message only occurs once.

Attached is a screenshot of the alert message.

I know this may be a long shot, any ideas how to solved this problem?

Thanks,
Bruce

Make sure that the wx.App object is created before that statement is executed.

To avoid the wxWidgets Alert message, I did the following within tabcodeEditor.py

Changed:
if name == ‘main’:
app = MyApplication(TabCodeEditor)
app.MainLoop()

To:

if name == ‘main’:
app = MyApplication(TabCodeEditor)

# The following statements are added here (and removed from top of file)
# after the wxApp is created to avoid the following alert message.
#   Using wxPython 2.9.4.0, got the following wxWidgets debug alert message:
#       ..\..\src\common\stdpbase.cpp(49): asserts "traits"  failed in
#       wxStandPathsBase::Get() create wxApp before calling this
# Note: tabbedCodeEditor works (no alert message) using wxpython 2.8.12.0
# --------------------------------------------------------------------------
from modules import colorizer
from PythonCard import STCStyleEditor
import codePage

app.MainLoop()

The solution may not be the best, but it works.

Thank you Robin for your suggestion.
