Package: pngmeta
Version: 1.11-9
Severity: normal
File: /usr/bin/pngmeta
With file https://www.gutenberg.org/files/16713/16713-h/images/q248.png
(about 7 kbytes), running "pngmeta q248.png" gets a segfault.
I suspect some badness in that image, since some other programs don't
enjoy it either (xzgv "can't load", dillo "checksum error"), but I hoped
pngmeta would not segfault.
gdb gives a backtrace showing somewhere under the final
png_destroy_read_struct() call in pngmeta.c main().
