Comment 4 for bug 1321679

As discussed, this may be similar to the upstream split string problem that was workarounded successfully in UI Toolkit:
http://bazaar.launchpad.net/~ubuntu-sdk-team/ubuntu-ui-toolkit/staging/revision/1080

Another very big fix in many apps resulted from this UI Toolkit fix adding default keyword too:

The armhf crasher related to the split function is tracked at bug #1323997
