Dolphin GDB backtrace (cut)
Whenever I try to create a new folder by right click -> New -> Folder on Dolphin inside an external USB drive (FAT32, don't know if it matters), the application crashes (no KDE crash window).
Looking at the GBD backtrace (attached), it looks like a stack overflow in KIO
Can't reproduce the issue anymore (KDE Frameworks 5.20, Qt 5.6), so I guess this was somehow fixed. Closing
Closing for real.
