extra registrations create applications slowness

[Sebastien Bacher]

Binary package hint: appmenu-gtk

<ted> $ bustle-time nautilusmenus.bustle
  5784.1740 243 23.8032 org.ayatana.dbusmenu.GetProperties
   712.0370 1 712.0370 org.ayatana.dbusmenu.GetLayout
    75.0190 292 0.2569 org.ayatana.WindowMenu.Registrar.RegisterWindow
 That's a nautilus window opening.

<ted> bratsche, It seems odd that nautilus is registering 292 time though -- there's probably a bug there.

Here's a Bustle log showing the problem. It looks like Nautilus is registering for a full second (?!?!) in this case?

I forgot to comment that the bustle log was taken with the property globing dbusmenu branch. Here's the updated time results:

$ bustle-time nautlius.openwindow.bustle
  997.9790 2 498.9895 org.ayatana.dbusmenu.GetLayout
   81.5700 292 0.2793 org.ayatana.WindowMenu.Registrar.RegisterWindow
   76.6040 2 38.3020 org.ayatana.dbusmenu.GetGroupProperties

Is libdbusmenu not batching the the menu changes? If I read that bustle log correctly Nautilus is triggering a DBus call each time it touches the menu?

Not sure if this is connected, but I'm getting tons of warnings in ~/.xsession-errors when using Nautilus. This was just from some minutes of use:

test@test:~$ cat .xsession-errors | wc -l
945343
test@test:~$ cat .xsession-errors | grep -c "^$"
472656
test@test:~$ cat .xsession-errors | grep -c "G_IS_OBJECT"
392707
test@test:~$ cat .xsession-errors | grep -c "GtkLabel"
53948
test@test:~$ cat .xsession-errors | grep -c "PangoLayout"
19206

The warnings:
*) GLib-GObject-CRITICAL **: g_object_set: assertion `G_IS_OBJECT (object)' failed
*) GLib-GObject-WARNING **: g_object_set_valist: object class `GtkLabel' has no property named `ubuntu-local'
*) GLib-GObject-WARNING **: g_object_set_valist: object class `PangoLayout' has no property named `ubuntu-local'

Working just one hour in Nautilus caused the .xsession-error file to be 300 MiB large. No problems without appmenu-gtk.

FYI: ~/.xsession-errors no longer gets spammed by those warnings - well done! :-)
