Same problem on i865G host gx27c in freshly updated F24.
BTW, the restore previous session setting is not producing a restoring of the Konsole session left open on session close, only an empty desktop.
Konsole is restored on restart on gx27c, after having gotten it open via Alt-F2.
I filed a bug:
if there was already one, though, please close as a dupe (and tag the original with 'openqa'). Thanks!
The symptoms are similar to when plasmashell deadlocks, so getting a backtrace from the presumably-deadlocked plasmashell process may be helpful in diagnosing what's going on.
In order to preserve limited / filesystem space, I tried minimally following the instructions at https://fedoraproject.org/wiki/StackTraces by installing only gdb and plasma-workspace-debuginfo, but the instructions don't say how to find the coredump. The only one that looked right by name and timestamp is in /var/lib/systemd/coredump/core.plasmashell<blah>.lz4 (@23059K). Gdb complains about that file:
....lz4 is not a core dump. File format not recognized.
Now what do I do?
I found out how to disable core compression and generated a new core, except I got 5 KDE cores[1] rather than one. I tried on the one with plasmashell in the name, and gdb complains "No symbol table info available over and over and waits on me to tell it what next. :-(
