Exiv2 crashes when reading this PNG image found by a digikam user:
(pay attention when clicking under KDE, may also crash konqueror which is using exiv2 through a component)
Backtrace of command line tool (sorry, didn't manage to compile with debug info):
#0 0x00007ffff7ac8259 in Exiv2::Internal::PngChunk::parseChunkContent(Exiv2::Image*, unsigned char const*, Exiv2::DataBuf) ()

The image can be opened with GIMP, it contains valid image data.

Interesting, I didn't know that. What component are you referring to?
Indeed, according to the Debian package dependencies, some core KDE packages (kdelibs5, kdebase-runtime and others) depend on the streamanalyzer library (libstreamanalyzer0) which depends on libexiv2-5.
