Fedora 26 build okular-16.12.3-1.fc26.x86_64 1) Start okular with two pdf's ; okular foo.pdf bar.pdf 2) Close each tab separately with ctrl-w 3) Once both are closed, close the application (I'm using the alt-f4 binding on my wm to close it) 4) seg: Thread 2 "QDBusConnection" received signal SIGSEGV, Segmentation fault.
