[Bug 817792] [NEW] pkgstripfiles doesn't preserve permissions of png files

[Felix Geyer]

Public bug reported:

pkgstripfiles runs advpng which doesn't preserve file permissions.

For example in https://launchpadlibrarian.net/76159822/buildlog_ubuntu-
oneiric-i386.ksnapshot_4%3A4.7.0-0ubuntu1_BUILDING.txt.gz

-rw-r--r-- root/root     91025 2011-05-20 20:36 ./usr/share/doc/kde/HTML/en/ksnapshot/window.png
-rw-rw-r-- root/root     34949 2011-07-28 14:34 ./usr/share/doc/kde/HTML/en/ksnapshot/send-to-menu.png

send-to-menu.png has wrong permissions because advpng was able to
optimize it.
