** Description changed: + ##SRU information added by Jonathan Thomas## + Impact: Causes the nepomukstorage nepomukservicestub to often crash on login + The problem: Upstream had forgotten to initialize some member variables in the Nepomuk::Repository::Repository constructor. Due to this, if anything requested the use of the nepomuk storage service before the soprano backend was ready, a crash due to accessing uninitialized variables resulted. + Addressed by: Upstream committed a patch to the stable 4.4 branch that initializes the offending member variables. + Patch: http://websvn.kde.org/?revision=1123884&view=revision + Testcase: None available. It was much easier to see when apport was on, as this is a background service, but we were never able to get anything solid on how to reproduce. + Regression potential: Zero. It never hurts to initialize variables in the class constructor, especially when you know that they may be accessed before they are initialized elsewhere in the code. + ############################### + Binary package hint: kdebase-runtime I just try toi enable Nepomuki and after few second get crash.
