when it crashes it should have a dialog appear asking to submit a backtrace. Could you do that please? No, crash dialog does not appears (like in other crash of applications). Maybe you can provide alternative method to get it? I just sugest, that it crash at higher level than drKonqi works... ok, thanks I recorded my desktop and captured several crashes. You can see how to produce it also. https://www.dropbox.com/s/w1u9sq6i5oe02uy/KDE_bug_354751.mpeg?dl=0 In https://www.dropbox.com/s/w1u9sq6i5oe02uy/KDE_bug_354751.mpeg?dl=0 crash occurs at 30, 1:12, 3:09, 3:50, 4:15, 4:33 time if the crash report dialog doesn't appear and is reproducible, try to run plasmashell in gdb

extremely weird crash: it's occurring at the qWarning() when it complain that it can't find the modelChanged() signal of the dataSource (as very few dataengines have) checking the signal actually exists before trying to disconnect is perhaps good regardless, but this should really not crash O.o Git commit c8b9b852ef46f64a772140dbabb64fb952466fdf by Marco Martin. Committed on 11/11/2015 at 10:07. Pushed by mart into branch 'master'. check for slot existence before connecting or disconnecting since this is a blind connect to a slot that may exist or not exist, the new syntax can't be used, but check for the slot existence before attempting a connection M +2 -8 src/declarativeimports/plasmacomponents/plasmacomponentsplugin.cpp M +18 -8 src/plasma/datacontainer.cpp http://commits.kde.org/plasma-framework/c8b9b852ef46f64a772140dbabb64fb952466fdf KDE Plasma 5.4.3 will receive this fix?
