@jonas Someone in the KDE bug discussion pointed out that this is a known issue involving QT with a relatively straightfoward fix (as far as I can tell, but I'm nowhere close to an expert). Here is a discussion of the issue and a description of the fix:

@jonas It looks like this is a KDE issue: I posted something about it in the Arch Linux reddit and another user replied reporting the same problem with qmmp.

I've opened a bug report with KDE: https://bugs.kde.org/show_bug.cgi?id=483439

I'm running Arch Linux and just upgraded to KDE Plasma 6. Since then, any time I try to use the file browser (e.g., to load a folder), when I hit OK or Cancel, Strawberry shuts down completely. I figure that this has something to do with Plasma 6 and might get worked out as bug fixes come in, but does anyone know what might be causing this and if there's anything that I can do locally to be able to use the file browser?
