[TYPO3-debian] Debian installation an GIFBUILDER

[Rico Moorman]

Good morning everyone!

I recently encountered a strange behaviour of the GIFBUILDER object with 
  a new debian-sarge installation

I just installed clean debian-stable ... installed apache, php4, 
php4-gd, php4-mysql, mysql-server, imagemagick

when I now try to place a resized version of an image in the GIFBUILDER 
object I only get a dark (inverted) image

page.20 = IMAGE
page.20 {
  file = GIFBUILDER
  file {
   XY = 200,200
   10 = IMAGE
   10.file = fileadmin/someimage.jpg
   10.file.width = 100
   10.file.height = 100
  }
}

when I add an image below, like
page.20.file.5 = IMAGE
page.20.file.5 {
  file = fileadmin/someimage.jpg
}
without any resizing the not resized image is shown with correct colours

maybe you know what could cause that...

thank you very much in advance!
