Details:
This really looks like a GTK2 bug, but it's odd enough to mention in the
tracker anyway. Just in case people ask.
If an Intuos5 (PTH-650) is plugged in, my laptop's touchpad cannot be used to
select brushes: clicks on the PixbufList don't seem to be getting through at
all. It doesn't matter if the Brushes window is docked or undocked, and brush
groups can still be chosen with the laptop touchpad. The laptop touchpad works
elsewhere, and can be used for painting.
Does not affect the touchpad when an older Bamboo tablet (MTE-450A) is
connected instead.

The popup "quick" brush selector, and the toolbar dropdown's brush list, are
unaffected.
Commenting out the following lines in gui/brushselectionwindow.py restores the
expected behaviour in PyGTK:
## Support device changing with the same event as that used
## for brush choice:
#if not pygtkcompat.USE_GTK3:
# self.set_extension_events(gdk.EXTENSION_EVENTS_ALL)
Could this be a suitable workaround? There seems to be some cleverness in the
module for setting the device-specific brush at the point the button is
pressed.
GTK3 mode is unaffected by this bug; however if MYPAINT_ENABLE_GTK3 is not set
at runtime, the bug still presents when compiled with enable_gtk3=true.
