Break scheduled transactions string

There is a bug in
static int layoutText(QTextLayout *layout, int maxWidth)
from kpageview_p.cpp from kwidgetsaddons.
The method doesn't break strings that are too long. This patch
workarounds this by using LINE SEPARATOR character which is accepted by
QTextLayout::createLine().
