-c doesn't prevent redownloading in the event that the server cannot
support ranged requests, which is sometimes the case. If this is one of
those cases, then this is not a bug. Well, if the server does manage to
send file-size in advance, and we can determine we already have the full
file, then we should probably terminate the connection, but if the
server didn't send size either (or if the size was different), then wget
is behaving correctly.

So, you'd need to run wget with -d and send us the headers that wget
sends and receives, to determine whether or not this is a bug.
