absent program name in error messages to stderr

[Alexander Sashnov]

Binary package hint: tracker

I have trackerd in my gnome session.

In .xsession-errors I see messages:

---------------------------------------
Gtk-Message: (for origin information, set GTK_DEBUG): failed to retrieve property `GtkOptionMenu::indicator-spacing' of type `GtkBorder' from rc file value "0" of type `glong'
create pidfile failed: File exists
Warning: hotplug syncing disabled.
Disk space is low!
Disk space is low!
Disk space is low!
Disk space is low!
Xlib: extension "GLX" missing on display ":0.0".
Xlib: extension "GLX" missing on display ":0.0".
--------------------------------------

Gtk-Message, Xlib - is not related to this bug report.

This bug about "Disk space is low!" without specify program which prodeces this message.

Expected result:

Gtk-Message: (for origin information, set GTK_DEBUG): failed to retrieve property `GtkOptionMenu::indicator-spacing' of type `GtkBorder' from rc file value "0" of type `glong'
create pidfile failed: File exists
Warning: hotplug syncing disabled.
trackerd: Disk space is low! <====== with specify program name an begin of line
trackerd: Disk space is low!
trackerd: Disk space is low!

Xlib: extension "GLX" missing on display ":0.0".
Xlib: extension "GLX" missing on display ":0.0".
