wxGUI: frequent Pango-CRITICAL errors

[msieczka]

Using wxGUI I often get a following error on GRASS terminal:

(python:31970): Pango-CRITICAL **: pango_layout_get_cursor_pos: assertion `index >= 0 && index <= layout->length' fail

6.4 branch r37101, Debian stable amd64, python 2.5.2, wx 2.8.7.

We can't always get rid of such warnings, as some of them are due to the way that wxWidgets uses the underlying toolkit (GTK+ on Linux).

The GTK+ libraries (GTK, GDK, GLib and Pango) are known for being rather "noisy" (i.e. generating many warning/error messages). This is mainly to help developers identify bugs; having detected an error, the libraries will normally try to recover from it, but in the case of GRASS such bugs may be in the wxWidgets or wxPython layers rather than in GRASS itself.

The messages should only be of concern to the user if they correlate with the GUI failing to work.
