Problem description quoted from downstream bug report


Thunar-1.8.2-1.fc30 (currently installed on my machine) has two dbus files:

/usr/share/dbus-1/services/org.xfce.Thunar.service
[D-BUS Service]
Name=org.xfce.Thunar
Exec=/usr/bin/Thunar --gapplication-service
SystemdService=thunar.service

/usr/share/dbus-1/services/org.xfce.FileManager.service
[D-BUS Service]
Name=org.xfce.FileManager
Exec=/usr/bin/Thunar --gapplication-service
SystemdService=thunar.service

My reading of the second file is that it is intended to provide
org.xfce.FileManager service, either via systemd or dbus.

However, it appears to only work over systemd. If you do not run systemd, it
tries to but does not work over dbus, I guess because Thunar does not actually
register "org.xfce.FileManager" service, only "org.xfce.Thunar" one.

Here how it fails:

# time dbus-send --print-reply --session --dest=org.freedesktop.DBus
/org/freedesktop/DBus org.freedesktop.DBus.StartServiceByName
string:org.xfce.FileManager uint32:0
Error org.freedesktop.DBus.Error.NoReply: Did not receive a reply. Possible
causes include: the remote application did not send a reply, the message bus
security policy blocked the reply, the reply timeout expired, or the network
connection was broken.
real    0m25.010s
user    0m0.004s
sys     0m0.002s

Starting "org.xfce.Thunar" service works:

# dbus-send --print-reply --session --dest=org.freedesktop.DBus
/org/freedesktop/DBus org.freedesktop.DBus.StartServiceByName
string:org.xfce.Thunar uint32:0
method return time=1547237509.405417 sender=org.freedesktop.DBus ->
destination=:1.4218 serial=3 reply_serial=2
   uint32 2

The symptom of this problem is that applications such as Ristretto (image
viewer) and Thunderbird (mail reader) have a 25 second delay on startup.
