Specifically, the "libqt5widgets5" package seems to be at fault. If I revert only this package to the previous version Quassel works properly.

What is the value of $QT_QPA_PLATFORMTHEME on your system?

Did you also upgrade appmenu-qt5?

That environment variable is empty. I did upgrade appmenu-qt5; the installed version is 0.3.0+16.10.20160628.1-0ubuntu2~2.

One more question: do you have plasma-integration package installed? If Quassel somehow picks it up (via KF5?), then we may need to rebuild it against new Qt.

Can you please try plasma-integration_5.7.2-0ubuntu1_amd64.deb from http://ppa.launchpad.net/mitya57/ppa/ubuntu/pool/main/p/plasma-integration/ and check if it fixes the segfault? (That .deb is a no-change rebuild against new Qt.)

Thanks, with this version of plasma-integration Quassel and VLC do not crash.
