---------------------------------------------------------+------------------
 Windows binary of stable QGIS 1.0.2 crashes when a python plugin has a
 QgsMapToolEmitPoint based class emit a SIGNAL('canvasClicked(QgsPoint& ,
 Qt::MouseButton )').

 Note that I had the exact same problem when I compiled 1.0.2 from source
 on Ubuntu 9.10, appearantly due to incompatibility with the versions of
 Qt4 and SIP that ship with that distro. In that case, I could 'fix' it
 there by backporting the qgsmaptoolemitpoint code from 1.3 (where the
 signal's signature is changed to use a 'const QgsPoint&'). It seems likely
 that the problems are related.

 To reproduce:
 Connect the signal 'canvasClicked(QgsPoint& , Qt::MouseButton )' from a
 QgsMapToolEmitPoint instance to any slot, and click on the canvas with
 that maptool active.
