TYPO3 Core

Typo3 doesn't show thumbnails in some areas of the backend. Instead it shows a dead link image. The problem shows in the "filelist" menu (with option show thumbnails) and in the select box at page contents.

It works fine in the "images" submenu in the "file" menu. The install tool is also able pass most of the images tests. In the scaling test the GIF to GIF test fails but the other tests passes. The GD passes 5 tests. The install tool recognizes the ImageMagick as version 5.5.6. The webhotel running the Typo3 installation uses the ImageMagick installation for many other applications, which rules out a problem here.

I have searched a lot about thumbnail problems in Typo3. Usually it is the ImageMagick installation that fails. Since this is ruled out, I think it must be an error.

Som infomation I hope could be useful:
1) Test report from the install tool
2) Message posted on a user group
3) Debug info
--------------
1) The GIF-to-GIF test that fails reports the following:
"Your server: Reference:
15.9 K, 150x120 pixels 3.8 K, 150x120 pixels
File size is very different from reference
16296 3912
Note on gif_compress() function:
The 'gif_compress' method used was 'IM'.
Previous filesize: 15.9 K. Current filesize:15.9 K "

2) I have posted the error in the Danish User Group but didn't get any reply. Here is a link to my message:
