wxPython - blank frame in Ubuntu

I've written a basic application in wxPython. While it works fine under Windows, under Linux (Ubuntu 11.10), the frame will appear empty (except for a few small broken elements on the left hand side). There are no errors in the console. Just before running it, I installed wxPython as per http://wiki.wxpython.org/InstallingOnUbuntuOrDebian

Any ideas appreciated. 

class MainWindow(wx.Frame):
def __init__(self, parent, title):
    self.dirname=''

    # A "-1" in the size parameter instructs wxWidgets to use the default size.
    wx.Frame.__init__(self, parent, title=title, size=(400,500),style=wx.DEFAULT_FRAME_STYLE & ~ (wx.RESIZE_BORDER | wx.RESIZE_BOX | wx.MAXIMIZE_BOX))
    self.CreateStatusBar() # A Statusbar in the bottom of the window
    panel = wx.Panel(self, wx.ID_ANY)

    # Setting up the menus
    filemenu = wx.Menu()
    editmenu = wx.Menu()

    menuOpen = filemenu.Append(wx.ID_OPEN, "&Open"," Open an underway netCDF to load")
    menuAbout= filemenu.Append(wx.ID_ABOUT, "&About"," Information about this program")
    menuExit = filemenu.Append(wx.ID_EXIT,"E&xit"," Terminate the program")
    menuConfig = editmenu.Append(wx.ID_EDIT, "&Config", "Edit Configuration")

    # Creating the menubar.
    menuBar = wx.MenuBar()
    menuBar.Append(filemenu,"&File") # Adding the "filemenu" to the MenuBar
    menuBar.Append(editmenu,"&Edit")
    self.SetMenuBar(menuBar)  # Adding the MenuBar to the Frame content.

    #Sizer setup.
    sizer = wx.BoxSizer(wx.VERTICAL) #root sizer
    buttonSizer = wx.BoxSizer(wx.HORIZONTAL)

    #Buttons.
    self.buttonLoadData = wx.Button(panel, -1, "&Load Data")
    self.buttonAbort = wx.Button(panel, -1, "&Abort Load")
    self.buttonAbort.Enabled = False
    self.buttonLoadData.Enabled = False

    #Slider. Should probably be a floating point spin control.
    #self.sliderRate = wx.Slider(panel, -1, 5, 0, 100, wx.DefaultPosition, (380, -1), wx.SL_AUTOTICKS | wx.SL_LABELS)
    self.sliderRate = self.FloatSlider(panel, -1, 1000, 0, 5000, wx.DefaultPosition, (380, -1), wx.SL_AUTOTICKS | wx.SL_LABELS)

    #Log window.
    self.log = wx.TextCtrl(self, style=wx.TE_MULTILINE | wx.TE_READONLY)


    # Events.
    self.Bind(wx.EVT_MENU, self.OnOpen, menuOpen)
    self.Bind(wx.EVT_MENU, self.OnExit, menuExit)
    self.Bind(wx.EVT_MENU, self.OnAbout, menuAbout)
    self.Bind(wx.EVT_MENU, self.OnConfig, menuConfig)
    self.Bind(wx.EVT_BUTTON, self.OnLoadButton, self.buttonLoadData)
    self.Bind(wx.EVT_BUTTON, self.OnAbortButton, self.buttonAbort)
    self.Bind(wx.EVT_SLIDER, self.OnSlider)

    #Subscribe to messages from underlying simulator
    Publisher().subscribe(self.updateDisplay, "update")

    #Layout sizers
    buttonSizer.Add(self.buttonLoadData, 0, wx.ALL, 5)
    buttonSizer.Add(self.buttonAbort, 0, wx.ALL, 5)
    sizer.Add(buttonSizer, 0, wx.ALL, 5)
    sizer.Add(self.sliderRate, 0, wx.ALL, 5)
    sizer.Add(self.log, 1, wx.EXPAND, 5)

    panel.SetSizer(sizer)
    panel.Layout()

You might have forgotten to add sizer.Fit(panel) in between of SetSizer and Layout to make sure wxPython calculates the layout properly. I do not know why it's working on Windows, but on Linux I wasn't able to make wxPython show frames correctly without Fit:

    panel.SetSizer(sizer)
    sizer.Fit(panel)
    panel.Layout()

This should do it.
