Lock in os.path.abspath() while using wxPython ?

[Laurent POINTAL]

Python 1.5.2
wxPython 2.2

Hello, we are using wxPython (started and running in Python main
thread), and we create a working thread. In the working thread a call:
  self.fname = os.path.abspath(filename)
result in a long lock... which is unlocked when we close the wxPython
main window (and a-priori exit event loop).

What could it be?

We know about Python global lock, but it seem to be another problem.

Thanks.
