By default, the module creates creates a directory using G_tempfile() 
which creates a temp path in the current mapset directory and G_mkdir() 
which creates a directory using that path.

Looking at you path (/media/fd/Dados...) it looks like you're using an 
external disk ? Maybe the mount options for this disque do not allow the 
creation of a directory with this name ?

Try launching 'mkdir 
/media/fd/Dados/FilipeTrabalho/FCT/FCT/fct/.tmp/fd-XPS/16123.0' and see 
what happens?
