--- Comment #15 from Deri James <d...@chuzzlewit.myzen.co.uk> ---
I am running Mageia (Cauldron) with 5.8.1, have the same problem. I ran
activity pager under plasmawindowed using gdb, after installing the debug
package for libqt5core5. This is the backtrace I got after the SIGSEGV, hope it
is useful for you.

Let me know if you need any further debug packages installed to get a useful
trace.
