The debugger often fails with error:

---
>[LOG]PythonDebugger : overall Starting
[LOG]PythonDebugger.taskStarted : I am Starting a new Debugging Session ...
[LOG]This window is an interactive debugging context aware Python Shell 
[LOG]where you can enter python console commands while debugging

The code causing the error is:

# -*- coding: cp1250 -*-
print "Hello World"

Removing the line, disabling the coding instruction (by changing it into cAAAoding) or changing coding to utf-8 fixes
the error and debugging starts normally. Sometimes the first start is successful but the following runs fail even if the
source wasn't changed at all. The normal run works fine, debugging in Eclipse or PythonWin works fine too.
