Hi,
I'm currently packaging owfs for openSUSE and got a bug report that in the
package with systemd enabled owfs crashes as soon as one browses the /run/owfs
folder with dolphin (KDE file manager).
Browsing the folder with ls works just fine.
To reproduce this I started owfs with the following parameters:
/usr/bin/owfs -u --server=127.0.0.1 --allow_other /run/owfs
The Backtrace looks like the following:
