QDom: Do not crash on "<a:>text</a:>"
"a:" is not a valid tagname. The function creating the element node
notices that and returns 0, but the parser ignores it and continues,
and then crashes later when processing the "text". This patch aborts
the parsing immediately when creating the element node failed and
fixes the crash.
