Another example of this:

User error: ImageMagick reported error code 1. Message: convert: unable to open image `sites/default/files/workspace/logos/Mdaillon IO en transition 290x152.png': gick-6.6.0/modules-Q16/coders/png.la @ error/blob.c/OpenBlob/2489. convert: unable to open image `sites/default/files/workspace/logos/Mdaillon IO en transition 290x152.png': @ error/blob.c/OpenBlob/2489. convert: unable to open file `sites/default/files/workspace/logos/Mdaillon IO en transition 290x152.png' @ error/png.c/ReadPNGImage/2951. convert: missing an image filename `sites/default/files/imagecache/thumb-medium/workspace/logos/Mdaillon IO en transition 290x152.png' @ error/convert.c/ConvertImageCommand/2940. in _imageapi_imagemagick_convert_exec() (line 235 of /web/transitionnetwork.org/www/sites/all/modules/imageapi/imageapi_imagemagick.module).

What is needed is for file names to be turned into US ASCII before the thumbnails are generated from them, or perhaps imagemagick can be made to work with UTF8 filenames?

Or perhaps I can fix it at a server level, see http://drupal.org/node/352262 I'll test this on the dev server and if it works apply it to the live server.

Or, provided you can install the high quality version (not usually in the repository for Debian without adding another source) we can switch to the GD library?

The suggestion of setting LANG in /etc/init.d/apache2 didn't work, it was still C, but setting it in /etc/apache2/envvars does work, see https://kiwi.transitionnetwork.org/info/

However this didn't fix the problem.

What did was editing sites/all/modules/imageapi/imageapi_imagemagick.module and adding a new line 153:

  setlocale(LC_CTYPE, "en_GB.UTF-8");

I have committed this to the trunk after testing it on the dev server:

Jim - are you OK deploying it to live?

just before:

  $command = escapeshellarg($source) .' '. implode(' ', $args) .' '. escapeshellarg($dest);

Yes no probs... I've got some more updates to do early next week so it'll get done then.
