This is a bug that should be fixed in the next version of abrt
packages.
Upgrading abrt
packages to version 2.11.1-2.fc29
is the root cause.
Bug : GLib-CRITICAL: g_child_watch_add_full: assertion 'pid > 0' failed
Background information and the temporary - proven to work - solution :
There's a file being located in /etc/xdg/autostart, that seems to be responsible for the problem.
This is the symbolic link file : /etc/xdg/autostart/org.freedesktop.problems.applet.desktop
The file is a symlink to /usr/share/applications/org.freedesktop.problems.applet.desktop
.
Delete the weird folder either by using the command line, or in the nautilus
application.
Then execute sudo rm /etc/xdg/autostart/org.freedesktop.problems.applet.desktop
.
Next time after restart of the system, you won't see newly created weird folders anymore.
Update Information 2019-01-16 :
Bugfix available : abrt-2.11.1-3.fc29
has been pushed to the Fedora Updates System.
No new strange folders get created anymore - but to get rid of the journalctl
message
GLib-CRITICAL: g_child_watch_add_full: assertion 'pid > 0' failed - the link file still has to
be deleted -> sudo rm /etc/xdg/autostart/org.freedesktop.problems.applet.desktop
.
