It's on LInux.

Performance really cannot be the issue, as I have another Python program
which does pretty much the same "work", using command-line user interface
instead of the wxPython GUI. This CLI program consumes about 3-5% of CPU on
the E3930.

I have never really worked with debuggers. Any hints or suggestions on
how/where to start?
