debsums reports mismatch for four PNG files

[Hernando Torque]

debsums reports those four PNG files being changed:

/usr/share/gnome/help/gparted/ru/figures/gparted_window.png
/usr/share/gnome/help/gparted/sl/figures/gparted_window.png
/usr/share/gnome/help/gparted/sv/figures/gparted_window.png
/usr/share/gnome/help/gparted/th/figures/gparted_window.png

According to the build log, other PNG files were optimized too, but debsum doesn't report those, so I don't think this is a problem with OptiPNG.

From checking the upstream repository, the four files listed above do not exist and have not been checked into git.

Upstream Repository:
http://git.gnome.org/browse/gparted/

For these translations to be complete, a location specific screen shot of gparted_window.png is required.

Perhaps the fact that these files are missing is causing the report of mismatch for four PNG files?

[Hernando Torque (htorque)]

No idea, they are in the Ubuntu sources though (only bigger in size, as they get optimized during build time, but so do others which don't show up as changed).

I filed similar bugs about changed PNGs files (bug 936367, bug 936368, bug 936369, bug 936370) and all files are located somewhere in '/usr/share/gnome/help'.

[Curtis Gedak (gedakc)]

Where in the Ubuntu sources did you observe these files?

I checked in the bazaar source repository for one of these files, namely "help/ru/figures/gparted_window.png" and I did not observe the file. The link I looked at in bazaar is as follows:
http://bazaar.launchpad.net/~vcs-imports/gparted/master/files/head:/help/ru/

[Hernando Torque (htorque)]

Oops, you are right - those reported files all are just symlinks to the "/usr/share/gnome/help/.../C/"-variant.

[Daniel Letzeisen (dtl131)]

Isn't this expected behavior? You modified files belonging to a .deb package, so the md5sum is going to change.

If Optipng is modifying files belonging to a .deb and debsums isn't complaining, then shouldn't you file one bug against debsums (or individual bugs against those packages instead of the ones that debsums is correctly identifying)?

[Hernando Torque (htorque)]

I didn't modify those images, they are optimized during the build process (likely to save valuable disk space :-)). I don't think I'm supposed to expect complaints from debsums after installing a package from the Ubuntu repos.

[Curtis Gedak (gedakc)]

From an application developer point of view I don't think that I can address these package debsums.

Perhaps Dave Lentz is correct that these bug reports belong to the packaging process. There might have been a recent change in the packaging process that is causing these debsums to surface.
