Git commit b1a9916a40c829d9b6430fee83b29ad70cedd1c7 by Simeon Bird. Committed on 28/04/2013 at 03:46. Pushed by sbird into branch 'KDE/4.10'. Nepomuk kded module: Properly null m_queryInterface after deletion. In case creating a new interface failed, we would be left with a dangling pointer, potentially causing a crash on destruction.
