The bug that was fixed (in 7.3.1, I believe) is this one:
http://bugs.slimdevices.com/show_bug.cgi?id=5119

To briefly summarise: if the replaygain vaue is positive and applying
that positive gain would cause clipping, then it should be scaled back
to prevent clipping. (A typical example would be classical music which
has a low average volume but has a few peaks at or around 0dB).

However, the screen shot posted by blkmagik98 appears to show something
has gone horribly wrong. The album gain is -5.4dB, and it says it's been
adjusted to -18.06dB to prevent clipping. If the replaygain is negative
(as in this case), then clipping cannot be introduced, so no adjustment
should be made.

Assuming the bug fix is applying the expected calculation based on the
replaygain tags, then it suggests the file has a REPLAYGAIN_ALBUM_PEAK
tag value of 8. That value should always be 1 or less (except in some
pathalogical cases with MP3, where it might be a little bit more than
1). You should check the value of this tag with a suitable program
(such as MP3Tag, Foobar2000, etc). If it is 8, then whatever program
added the replaygain tags has made an error. If it's 1 or less, then
the error appears to have been made either during the SqueezeCenter
scan or in the clipping prevention calculation that was added in the
bug fix.
