IMO that's a desireable behaviour, not a bug. See Bringhurst, Oliver Simon's _Introduction to Typography_ &c.
A control to turn it off or on (defaulting to disabling the ligatures) would be okay, but I've had to put a lot of effort into turning off ligatures when letterspacing and it's a pain.
In older german texts ligatures are not letter spaced. For example:
B i s m a r ck
(the ck ligature is not seperated)
Neither was ij in dutch, but ff was separated. Which just goes to show you that doing letterspacing automatically is hard....
