            Bug ID: 404218
           Summary: Upgrading kf5-kcmutils to 5.54.0-1 (x86_64) causes
                    several applications to fail on launch
           Product: frameworks-kcmutils
           Version: 5.54.0
          Platform: Fedora RPMs
                OS: Linux
            Status: REPORTED
          Severity: grave
          Priority: NOR
         Component: general
          Assignee: kdelibs-b...@kde.org
          Reporter: to...@mediastampede.com
  Target Milestone: ---

SUMMARY

After the Fedora 29 package manager upgraded kf5-kcmutils to version 5.54.0-1
(x86_64) from 5.50.0-1, several applications including dolphin, konqueror and
systemsettings5 fail to launch, with an "undefined symbol" error. In addition,
KInfoCenter fails to install via dnf, with an identical error.


STEPS TO REPRODUCE
1. Upgrade kf5-kcmutils to version 5.54.0-1 (from 5.50.0-1)
2. Attempt to launch dolphin, konqueror or System Settings from Application
Launcher: application fails to present GUI; no error message 
3. Attempt to launch above three applications from konsole; an undefined symbol
error results, as detailed below.

OBSERVED RESULT
All misbehaving applications generate the same error from konsole...

symbol lookup error: /lib64/libKF5KCMUtils.so.5: undefined symbol:
_ZN12KQuickAddons12ConfigModule19currentIndexChangedEi


EXPECTED RESULT
Application launches and presents a GUI


SOFTWARE/OS VERSIONS
Windows: 
MacOS: 
Linux/KDE Plasma: 5.14.4-2 (guessing from plasma-desktop version, since neither
System Settings nor KInfoCenter are usable.
KDE Plasma Version: 5.14.4-2 (unclear on this, see above)
KDE Frameworks Version: 5.54.0-1
Qt Version: 4.8.7-44

ADDITIONAL INFORMATION
Upgrading kf5-kcmutils to version 5.55.0-1 doesn't fix the undefined symbol
error.

libKF5KCMUtils.so.5 points to libKF5KCMUtils.so.5.54.0 in /usr/lib64 under
version 5.54.0-1; another libKF5KCMUtils.so.5 symbolic link to a duplicate (as
far as I can tell) libKF5KCMUtils.so.5.54.0 in /lib64

Rolling back kf5-kcmutils to version 5.50.0-1 fixes all issues, as far as I can
tell. RPM requires no other changes on the rollback.

NOTE: I'm a newbie to bug reports, apologies in advance for inadequate,
inaccurate, or too much info. I'm not afraid of the command line.
