Try to enable it then. Apparently it is crashing when trying to start kwalletd... The crash has already been reported though. 1616380 4 wbauer1 2016-08-23 20:33:54 +0000 *** Bug 365456 has been marked as a duplicate of this bug. *** 1618671 5 wbauer1 2016-09-02 14:54:24 +0000 *** Bug 368152 has been marked as a duplicate of this bug. *** 1619030 6 wbauer1 2016-09-04 18:20:28 +0000 I tried it myself now, and I can confirm that the crash indeed happens when kwallet is disabled.
