I don't know what's happen (it seems an issue with the database) but if
you want to catch the error when committing, you have to know that the
function mapper.submit() return true if the operation is ok, or false
otherwise. So, to catch an exception:
if not mapper.submit():
# using the .text() function return the error as string
print "Error on committing: %s" % (model.lastError().text())
print "Everything is ok!"
In some cases, for example if you delete some records, you need to use
the model.submit() function instead.
