I guess (I haven't actually "fixed" the situation yet) that the file 
conflict is resolved, but something is different then normal because 
SONAME bumps and new binary names normally don't cause apt to "keep 
back" the old binaries. I don't totally understand, I'm very much 
guessing it related to a simultaneous SONAME bump in one of the reverse 
dependencies. Just reporting in case others see something worse.
