I decided to reboot my mybook and noticed that transmission had not automatically started as it usually does.
Upon starting it manually I was informed that it could not find some necessary libraries that were not previously required. Notably libintl and libiconv.
I installed gettext to get libintl, and libiconv is in the optware stream. Were these always required? I don't think so cause I had a look at my old ldconfig -p and there was no sign of either library. Hopefully if others encounter these problems they will easily be fixed.
P.S. I'm on firmware 2.00.15
