## Observation

openQA test in scenario opensuse-Tumbleweed-DVD-x86_64-yast2_gui@64bit fails in
[yast2_control_center](https://openqa.opensuse.org/tests/653259/modules/yast2_control_center/steps/25)
not opening an UI for configuring software repos or something.

y2log has some errors included:

```
2018-04-09 13:01:12 <3> susetest(3352) [ui] YUIPlugin.cc(YUIPlugin):50 Could
not load UI plugin "qt_zypp_solver_dialog": libyui-qt_zypp_solver_dialog.so.8:
cannot open shared object file: No such file or directory
2018-04-09 13:01:12 <3> susetest(3352) [qt-ui]
YQZyppSolverDialogPluginStub.cc(YQZyppSolverDialogPluginStub):69 Plugin
qt_zypp_solver_dialog does not provide ZYPPP symbol
```

## Reproducible

Fails since (at least) Build
[20180314](https://openqa.opensuse.org/tests/635909)


## Expected result

Last good: [20180313](https://openqa.opensuse.org/tests/633732) (or more
recent)

That error messages sound like something that should not be there but of course
it could be that they do not describe what is happening here. Nevertheless, we
should not become GTK and gnome with all its "CRITICAL ASSERTION FAILED" but
then it behaves fine ;) So I suggest to treat these errors seriously and either
solve the problem or prevent these logs to appear as errors.



## Further details
