[TYPO3-core] RFC #13283: Thumbnail generation broken for PDF files

[Ernesto Baschny [cron IT]]

Hi,

I have had the latest Stucki-Patch running on some of our hosting
environments where we had experienced the "GS 100% CPU hung-ups" while
processing PDFs, and it solves the problem.

Haven't analysed what it means for "noFramePrepended" setting, but as
even Steffen Ritter was convinced by Stucki about it, I would say it is
good.

So +1 on testing.

Cheers,
Ernesto
