Just read in imagemagick's changelog that new package libmagick++5.5.3c102 (g++ 3.2 ABI) Provides: libmagick++5 (g++ 2.95 ABI). Shouldn't this be reported as a serious bug? This will cause blind upgrades from old libmagick++5 (that is in Woody) to a library with an incompatable ABI, causing all software (not locally-built, but installed from Debian!) linked to the library to break.
