Public bug reported:
On Ubuntu 24.04, libexiv2-27 upgraded today to 0.27.6-1ubuntu0.1. After this
upgrade, gimp would fail to open files that it had previously opened without
issue. The exact message would vary, but for a PNG file, it would be something
like:
double free or corruption (out)
/usr/lib/gimp/2.0/plug-ins/file-png/file-png: fatal error: Aborted
Attaching gdb to the file-png process produced a stack trace that included
libgexiv:

Downgrading libexiv2-27 to 0.27.6-1build1 fixed the problem.
I'm not sure if this is a problem in libexiv itself, or a sign that
libgexiv needs to be recompiled against the newer libexiv. I'm
reporting it here in the hopes that you can get it to the right place if
I got it wrong.
