Maybe related? My Plasma Desktop crashes occasionally (visible outcome: spontaneous restart). I'm tracing this problem back to the following line that appears in the "dmesg" output: [46659.021516] kactivitymanage[1638]: segfault at 7faabe1bbcd0 ip 00007faaa41f01b1 sp 00007ffdd86a0258 error 4 in libQt5Sql.so.5.4.2[7faaa41dc000+3f000]
This has been revamped. The crashes should not appear any more (at least, not here ;) )
(current master, will be in the next release of frameworks)
