Bug 374473

Running Fedora 25, KDE desktop. Machine was upgraded from 23 to 24 then to 25 in the last month or so. The crashes started shortly after upgrading to f25 but reported a link back to f23. 

The desktop crashes randomly - logging out the user and closing applications. There doesn't appear to be any obvious trigger for the crash. The kactivitymanagerd error says data are incomplete and can't file a report. The core dump process seems to have locked up.

Applications "involved" in the crash are:
xorg-x11-server   1.19.0-2.fc25x86_64
kdepim            16.08.3-1.fc25.x86_64
plasma-desktop    5.8.4-1.fc25.x86_64
kdepim-runtime    1:16.08.3-1.fc25.x86_64
kactivitymanagerd n/a
drkonqi           n/a
