No, the problem is rather that the new version of kimageannotator bumps
the SONAME of the shared library from libkImageAnnotator.so.0.3.2 to
libkImageAnnotator.so.0.4.0, which is a big no-no. This also means that
kimageannotator sets the SONAME of its shared library to the full
version number, basically breaking compatibility even in patch
releases; this is _bad_...
Also, the Debian packaging of it does not help detecting this kind of
situations, as names the library package as if the SONAME was only "0":
$ lintian -I -E --pedantic --no-tag-display-limit
libkimageannotator0_0.3.2-2_amd64.deb
W: libkimageannotator0: package-name-doesnt-match-sonames
libkImageAnnotator0.3.2
I: libkimageannotator0: no-symbols-control-file
usr/lib/x86_64-linux-gnu/libkImageAnnotator.so.0.3.2
