SUMMARY
Sometimes a list of grouped windows has empty entries.
I can't reproduce these behaviors consistently, but it occurs 90% of the times after I follow the steps below.

STEPS TO REPRODUCE
1. open one window of chromium browser (I can't reproduce with Firefox)
2. press ctrl+n to open another chromium window (now you have two chromium windows)
3. open konsole
4. press ctrl+shift+n three times to open new instances of konsole (now you have 4 konsole windows) 
5. open another app (Kate, for example) via the apps launcher
6. click the group of konsole windows
7. click the group of konsole windows again to close it
8. click the group of chromium windows

OBSERVED RESULT
list of grouped chromiums shows empty entries.
See the screenshot.

EXPECTED RESULT
no empty entry

Does it happen with Qt 5.12.x?

Reproducible with Qt 5.12 on neon dev unstable.

I have the same issue, on Neon (user, with last updates) and Fedora 30 (29 with Qt 5.11 also had it).

Probably a regression caused by https://commits.kde.org/plasma-desktop/ab26ebb18b74d8def8e653dc94516fa7da935a5c
