Bug#546668: python-brasero: Packaged example script aborts with GLib-ERROR

[Andrew Price]

Package: python-brasero
Version: 2.27.3-1
Severity: normal

  andy at plato:braseromedia$ pwd
  /usr/share/doc/python-brasero/examples/braseromedia
  andy at plato:braseromedia$ python drive_selection.py 

  GLib-ERROR **: The thread system is not yet initialized.
  aborting...
  Aborted

This happens on line 9 of drive_selection.py which is:

  monitor = braseromedia.MediumMonitor ()

Afterwards I installed the brasero package from experimental to check if
it was a common problem but I successfully burned a CD with brasero.
Running the example script after installing brasero pulled in its deps
also gave the same error.

Here's a nice ugly backtrace. Line #6 looks interesting:
