TYPO3 Core

Can you please provide the full TypoScript that resulted in this warning?

Hi, for example such conf
lib.content = IMAGE
lib.content {
file = GIFBUILDER
file {
XY = [10.w],[10.h]
10 = TEXT
10 {
offset = 0,15
text = TEST
fontSize = 21
fontColor = #000000
}
}
}
produces that warning, I've uploaded screenshot

UPDATE
Just double checked again – the warning being produced only in ver. 4.3!

it occures in this part, when var $file contains string 'GIFBUILDER':

class.tslib_content.php:
...
$theImage = $GLOBALS['TSFE']->tmpl->getFileName($file);
// If image was processed by GIFBUILDER:
// ($imageResource indicates that it was processed the regular way)
if (!isset($imageResource) && $theImage) {
$gifCreator = t3lib_div::makeInstance('tslib_gifbuilder');
/* @var $gifCreator tslib_gifbuilder */
$gifCreator->init();
...

I can confirm the problem description and effects.

Same here.

Looking at the admin panel when using graphical headers and/or teasers made by the ICEpack shows lots of these errors in 4.3.4

I can confirm the problem description and effects on 4.4.4

This problem is still there in version 4.5.2
