It would be better to route g_log() and g_warning() messages
to Pan's Tools|Log Viewer window, at least on Windows:

* writing to the console pops up a console window behind the
  app, which is annoying to Windows users and hard to capture
  output from.
* by writing the output to the Log Viewer, users can save the
  messages in a text file that can be attached to bug reports.

on news.software.readers:

> Capturing screens using "Alt-PrintScrn" only saves HUGE .bmp files.
