Where exactly do you see that? Does it appear in any of the log files?

That looks like a real bug. I can't reproduce it here because the
warning was only added in a fairly recent glib version (the one for
GNOME 3.12).

    gmain: Warn when g_source_remove() fails
    
    Trying to remove a non-existent source should really be
    a programming error, as the programmer could be trying to
    use the wrong function to remove a callback, as seen when
    GtkScrolledWindow tried to remove ID from another function
    using g_source_remove().

Can you try to track it down?

Attached is a test program which should trigger the warning. Compile
with:
gcc -g -o test-remove test-remove.c `pkg-config --cflags --libs glib-2.0` 

Then run with
G_DEBUG=fatal_criticals gdb ./test-remove
$ run
[crash]
$ where

At least I think it'll crash, thanks to G_DEBUG=fatal_criticals.

Once you can catch it like this, try the same with syncevo-dbus-server
(assuming that this is where the problem occurs - see my question
above).
