Any hints how to reproduce this behavior? I used the following TS on
Ubuntu / GraphicsMagick and the quoting results were the same before and
after the patch (both correct).

page.130 = IMAGE
page.130 {
  file = GIFBUILDER
  file {
    XY = 200,50
    format = jpg
    quality = 88
    backColor = #FFFFFF
    10 = TEXT
    10 {
      text = Hallo Weltas!
      fontColor = #000000
      fontSize = 38
      fontFile = fileadmin/Acapulco.ttf
      offset = 0,40
    }
    20 = SHADOW
    20 {
      blur = 30
      color = #FF00FF
      textObjNum = 10
    }
  }
}


Result:
Array
(
    [0] => +profile
    [1] => '*'
    [2] => -compose
    [3] => over
    [4] => +matte
    [5] => 'typo3temp/temp/a885e075fed9608a611a2ea024b2a869_menu.gif'
    [6] => 'typo3temp/temp/a885e075fed9608a611a2ea024b2a869_color.gif'
    [7] => 'typo3temp/temp/f9702ffd24d69faf71be62210fd6d47f.gif'
    [8] => 'typo3temp/temp/a885e075fed9608a611a2ea024b2a869_menu.gif'
)

Best regards,
