[Bug 923407] [NEW] pkgstripfiles: md5sum incorrect when advpng fails

[Felix Geyer]

Public bug reported:

The md5sum is not updated when advpng fails but optipng ran fine.

This happened with the gquilt 0.25-2 package:
Unexpected PLTE chunk on ./usr/share/pixmaps/gquilt/stock_finish.png [at void throw_png_error():pngex.h:37]
WARNING: advpng failed on ./usr/share/pixmaps/gquilt/stock_finish.png, ignoring

Then lintian says:
E: gquilt: md5sum-mismatch usr/share/pixmaps/gquilt/stock_finish.png


>	if ! optipng -o4 -preserve "$f"; then
>	    echo "WARNING: optipng failed on $f, ignoring" >&2
>	    continue
>	fi
>	if ! advpng -z4 "$f"; then
>	    echo "WARNING: advpng failed on $f, ignoring" >&2
>	    continue
>	fi

The second continue statement needs to be removed.
I'm not sure why the first one is there, mabye both should be removed.
