Another user experienced a similar problem:

Testing crash report with updated libreport/abrt, not a genuine report.

reporter:       libreport-2.6.3
backtrace_rating: 3
cmdline:        kwrite
crash_function: __kernel_vsyscall
executable:     /usr/bin/kwrite
global_pid:     2490
kernel:         4.2.3-300.fc23.i686
package:        kwrite-15.08.1-1.fc23
reason:         kwrite killed by SIGSEGV
runlevel:       N 5
type:           CCpp
uid:            1000
Comment 13 Kevin Kofler 2015-10-29 01:04:56 UTC 
Now, artificial or not, why does this kwrite crash reach ABRT to begin with? All crashes (and that includes "crashes" from something like "killall -SIGSEGV kwrite") in KDE GUI apps should be caught by DrKonqi and never get to ABRT!
Comment 14 Adam Williamson 2015-10-29 01:08:57 UTC 
I don't think I've seen a KDE crash handler in all my 23 Final testing, all crashes (including the ones we fixed as blockers) went to abrt.
Comment 15 Adam Williamson 2015-10-29 01:09:56 UTC 
neither kde-runtime-drkonqi nor plasma-workspace-drkonqi is in 23 Final RC6 KDE 32-bit live.
Comment 16 Adam Williamson 2015-10-29 01:10:42 UTC 
'drkonq' doesn't appear in comps-f23.xml.in or spin-kickstarts.
Comment 17 Kevin Kofler 2015-10-29 01:20:56 UTC 
Which sounds like a bad bug in the spin kickstarts which is going to get us flooded with bug reports that should go upstream instead. :-(

This regression was introduced when Rex Dieter removed the hard dependency on DrKonqi to allow users to work around bugs in DrKonqi that way.
