Comment # 8 on bug 1092329 from Matthias Gerstner

Did you find something by now (given your submission referencing this bug)?

In the attachment you can find the log of plasmashell running in the
foreground. I started it from a sane shell without leaked FDs. A konsole
started from this plasmashell had leaked FDs again.

It's easily reproducible in my virtual machine setup for the current Leap 15
RC. Initially I did a clean install with KDE desktop environment, logged into
plasma, started konsole and there it was.

I tested with disabled sound notifications (as far as I found this possible)
and with enable qemu sound emulation but the situation did not change with
regard to the leaked sockets.
