Description of problem: Wine uses the libpng16.so file, but there is nothing in the RPM package that ensures it is installed. Obviously it is not an ELF dependency; I'm guessing it is something windowscodecs.dll.so explicitly dlopen() or something like that. Anyway, libpng is needed for wine to work properly. So adding an RPM "requires" on libpng%{?_isa} dependency in wine-core does seem to make sense, doesn't it?
Perfect assessment: dlls/windowscodecs/pngformat.c:202: if((libpng_handle = wine_dlopen(SONAME_LIBPNG, RTLD_NOW, NULL, 0)) != NULL) { Fix pushed as 1.7.16-2 for rawhide. Will fix the other branches tomorrow.
