I think I found the issue. In my main dialog, which is build from a glade 
xml file, I defined these signals:

  on_dialog_key_press_event
  on_dialog_key_release_event

Then, in my code, I build a dict with all signals, including these ones:

  signalDict = "on_dialog_key_press_event": self.__onKeyPressed,
               "on_dialog_key_release_event": self.__onKeyReleased,
               ...

Doing this crashes the application on maemo OS2008 (but works on OS2007!). 
If I add the code:

  self.dialog.connect("key-press-event", self.__onKeyPressed)
  self.dialog.connect("key-release-event", self.__onKeyReleased)

then it works in any case.

BUT... the first config (definig signaks in the dict), which crashes my 
main dialog, is also used in a secondary dialog, and works fine there!

I think there is a problem in the xml glade file, as I often (but not 
always) have a nasty bug: just opening the File menu crashes the 
application (on all maemo OS).

I'm puzzled. It seems there is several issues, and I can't find any infos 
about all that. And I don't even know how to debug such problem...

Thanks for any idea.
