Bug 469719

SUMMARY
After double-click on Juk icon, Juk takes ~5 minutes to show up on the screen and then freezes saying "Not rresponding..." in its window decoration. I can't reproduce this bug when using another user account.

EXPECTED RESULT
Juk should be usable

SOFTWARE/OS VERSIONS
Operating System: Arch Linux 
KDE Plasma Version: 5.27.5
KDE Frameworks Version: 5.105.0
