Thanks for the bug report, the issue is "about to be fixed".

The "about to be" means, that AFAIK the %postun will be run from the package 
previously installed, so one will need two updates until the change takes 

Right now, I checked in a version without any %postun, which should be 
available soon, just to be sure there is no "bad" postun in the installed 

I will check in another package with the fixed %postun in a few days, hoping 
that most users will have received this "intermediate" update by then.
