Thanks for your reply.
Had a look at your suggestions and found that when tagging "appears" to fail, nothing is written to the terminal, however, the time-stamp is updated. GMB doesn't give any indication in the GUI that the tag has been changed until I tell it to re-read the tag.
In a nutshell the tags in flac files are being written but most of the time the library isn't reflecting the changes until the tags are re-read.
