wxPython on Linux error

I've been working with wxPython on a Solaris 2.8 machine and
I just moved my application to a Linux box to do some
development at home. Everything compiled and installed
fine, but when I run my application I get the following
error:

···

----------------------------------------------------
Traceback (most recent call last):
  File "./gt_csg.py", line 541, in ?
    app = MainApp(0)
  File "/usr/local/python/2.3/lib/python2.3/site-packages/wxPython/wx.py", line 1939, in __init__
    _wxStart(self.OnInit)
  File "./gt_csg.py", line 27, in OnInit
    self.GetFrame().AppendMenuItem("file", "&New", "Create a new file")
  File "/home/morrisde/py/rad/gui/App.py", line 145, in AppendMenuItem
    if (string.lower(string.replace(self.menuBar.GetLabel(ix), '&', '')) == string.lower(string.replace(menu, '&', ''))):
  File "/usr/local/python/2.3/lib/python2.3/site-packages/wxPython/windows.py", line 1031, in GetLabel
    val = windowsc.wxMenuBar_GetLabel(self, *_args, **_kwargs)
wxPython.wxc.wxPyAssertionError: C++ assertion "wxAssertFailure" failed in ../src/common/menucmn.cpp(950): wxMenuBar::GetLabel(): no such item
----------------------------------------------------

From all I can tell, wxMenuBar::GetLabel() *should* be

there, but wxPython thinks it is not.

System setup:
OS: Linux
Python: 2.3
wxPython 2.4.1.2 (internal-distrib wxWindows)

command-lines for the compile:

----------------------------------------------------

mkdir build

sudo ../configure --with-gtk --prefix=$WXPREF --enable-rpath=$WXPREF/lib \
    --without-opengl --enable-geometry --enable-optimise --enable-debug_flag

sudo make
sudo make install

cd ../wxPython
sudo python setup.py BUILD_GLCANVAS=0 WX_CONFIG=$WXPREF/bin/wx-config \
    build install

----------------------------------------------------

Any help on this?
