Subject: Make sure we get a valid accessibleInterface in child_helper.
X-Git-Url: http://git.silmor.de/gitweb/?a=commitdiff_plain;h=481e8bc63ccdb9b29dac69bde0344d9b9b7b217c;p=konrad%2Fqtdeclarative.git

Make sure we get a valid accessibleInterface in child_helper.

With filtering out more items from the tree of accessibles
make sure that if we get 0 returned we don't crash.
