Crash information from DrKonqi

SUMMARY
For a set of specific users, at login, plasmashell intermittently crashes.

Only those users with the following KDE Plasma environment are effected:
 * Desktop background is a single colour - grey.
All users have the Oxygen style and icons; they all have the Crystal White cursor.
Users with a photograph as the Desktop background do not suffer the crash.

Test users with Breeze style and icons and, the default openSUSE Desktop background also, do not suffer the crash.

STEPS TO REPRODUCE
1. Login

OBSERVED RESULT
KCrash: Attempting to start /usr/bin/plasmashell from kdeinit
KCrash: Application 'plasmashell' crashing...
KCrash: Attempting to start /usr/lib64/libexec/drkonqi from kdeinit
Missing separate debuginfo for /usr/bin/plasmashell
Try: zypper install -C "debuginfo(build-id)=ad29c16bbfda5ddc4b8befc2efeef645479b1da3"
Missing separate debuginfo for /usr/lib64/libKF5PlasmaQuick.so.5
Try: zypper install -C "debuginfo(build-id)=cf7f205bda4e3edb646020e53f0c5dbae615e71c"
Missing separate debuginfo for /usr/lib64/libQt5Script.so.5

EXPECTED RESULT
No crash.

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: openSUSE Leap 15.1
KDE Plasma Version: 5.12.8
KDE Frameworks Version: 5.55.0
Qt Version: 5.9.7

ADDITIONAL INFORMATION
Finally, DrKonqi popped up after the crash.
Trying to add the debug packages via DrKonqi didn't work - root password couldn't be decoded . . .
Added the debug packages by using the output of
"gdb /usr/bin/plasmashell <PID>".
DrKonqi still couldn't find enough symbols for a useful crash dump.
Maybe I'll have better luck next time.
Comment 1 Don Curtis 2019-07-25 09:15:19 UTC 
Further crash dump from today.
DrKonqi still not accepting the root password to load additional debug packages.

Application: Plasma (plasmashell), signal: Segmentation fault
