unsupported file format

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.

In addition, some JPEGs that were created/saved prior to 2.8.4, and JPEGs created via the dcraw/convert pipe, are now also "unsupported file format".

I have never experienced this trouble prior to the apt-get update.

Can anyone offer some suggestions.

TIA, Robert

By doing a simple copy changing the extension from "tiff" to "tif" [cp input.tiff output.tif] the file now opens.

Surely this is not correct *nix behaviour?

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

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

Both files have the same characteristics (which is to be expected).

"file input_image.tiff" (and "file output_image.tif") give: input_image.tiff TIFF image data, little-endian output_image.tif TIFF image data, little-endian

identify gives: input_image.tiff TIFF 3900x3900 3900x3900+0+0 8-bit DirectClass 45.66MB 0.000u 0:00.000 output_image.tif TIFF 3900x3900 3900x3900+0+0 8-bit DirectClass 45.66MB 0.000u 0:00.000

diff -s reports: Files input_image.tiff and output_image.tif are identical

I don't think there is any doubt that if Gimp opened one it should also have opened the other.

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

No, that is not possibel. Even if it were, both files can be opened by *every* other image viewing application living on my Ubuntu OS.

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.

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.

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