You can modify your source to:
if (!g_thread_supported ()) g_thread_init (NULL);

instead of:
g_thread_init (NULL);

I'll modify the gda_init() function to add that test myself, but you
can do that modification localy in libgda for now.

If you can't, then I'll have to modify the gda_init() function to
introduce optional inclusion of threading support, but I'd prefer not
do this since I want to introduce non blocking (asynchronous)
functions in libgda.
