Because of Harry's interruption, we don't know.... If Slughorn didn't 
mean to end his sentence with 'Voldemort' - what else might he have 
said instead? And what's with the 'but'?

hg:
I took it to mean that Slughorn thought Harry might be a Horcrux.  It 
might also at least a partial explanation as to why he's so reluctant 
to help Dumbledore before this point, and why he's offering the memory 
to Harry here, once he finds out Harry is the Chosen One.
