sorry to say the new snapshots don't work for me.

i've narrowed the problem down to this:

 >>> from PyQt4 import QtGui, Qsci
 >>> a = QtGui.QApplication([])
 >>> s = Qsci.QsciScintilla()
 >>> s.SendScintilla(s.SCI_SETUNDOCOLLECTION, 0)
 >>> s.setText('foo')
Segmentation fault

this is using:

gcc 4.4.1, python 2.6.5, qt 4.6.2, sip snapshot-4.10.3-f292793d6c99, 
pyqt snapshot-4.7.4-36c5fbec9a15, qsci snapshot-2.4.4-90e3461f410f
