Upgrades from 1.32.5-[23] are not going to be fixed. The fix was for upgrades 
from 1.32.5-1 and lower. Since 1.32.5-2 and -3 are never going to hit 
experimental, that is not a problem. Since you upgraded to 1.32.5-3, you'll have 
to get out of that situation yourself. You can do it by using dpkg and 
--force-depends / --force-breaks in order to override what dpkg doesn't want to 
do, and then going to a normal state again.
