Yes. dbus-glib operates in the default GLib main-context[1] and makes no
attempt to be thread-safe. If you are using dbus-glib, you should
iterate the default GLib main-context in the main thread (the one that
called main()), like you would for a Gtk application.

Additionally, you haven't said which version of libdbus this is. If it
is version 1.6.x then it has no thread-safety by default: you have to
call dbus_threads_init_default() as early as possible. Version 1.8.x
makes that function call unnecessary, but still harmless.

I recommend using GDBus instead of libdbus for multi-threaded D-Bus,
particularly if you are already depending on GLib.

This is not a useful backtrace: for a useful backtrace, you need debug
symbols. From that path you seem to be using either Debian or a Debian
derivative like Ubuntu, in which case installing dbus-1-dbg,
libdbus-glib-1-2-dbg and libglib2.0-0-dbg would be appropriate.
