Surely this is not correct *nix behaviour?

What's the output of the file command for this file?

Is it possible that somehow Ubuntu has adopted the Windoze convention that only three-letterextensions are valid?

I am using Gimp 2.8.4 which was updated for Ubuntu 12.04 (DreamStudio 12.04) via apt-get update. Since updating I am getting "unsupported file format" messages for photos converted from RAW by dcraw to the default ppm then piped through IM's convert utility into TIFFs.

Who is giving you that message when you do exactly what?

Gimp 2.8.4 when I attempt to open the file, either via menu --> file --> open, or from the command line using "gimp file.tiff".

Both methods work with "file.tif".

That is most weird, because gimp should open the file even if it had some totally different or no extension at all.

Can you check if ubuntu does some sort of patching to gimp 2.8.4?

That's a DOS convention - 32-bit Windows always supported extensions of any length.

Why don't you report it to Otto? He is quite responsive.

I agree, filenames are irrelevant to *nix. Magic numbers are used instead.

I don't have to check. Ubuntu patches *every* application. However, there has
been a big stuffup here. The version I have upgraded to (ie, the most recent
upgrade) is a ppa, "2.8.4-2precise0", by "otto-kesselgulasch". Prior to the point-upgrade to this version GIMP opened anything I cared to throw at it.

I have not reported this bug to Ubuntu because, even though I have been a Ubuntu
user since version 5.04 and meticulously follow the bug reporting procedure, I
have never been able to report a bug in a manner that is acceptable to the various maintainers. I have posted ithe bug in this forum in the hope that someone may have a workaround (or the ear of the maintainer).

For the moment I am tacking "cp intermediate.tiff output.tif" onto my initial
command line post-processing in order to produce a file that can be opened up in
GIMP for further visually- guided post-processing.
