Created attachment 126445 [details]
RTF-file with embedded jpeg

Opening the attached file 'logo_only.rtf' and saving it again as an RTF-file lets the filesize explode from 454kB to almost 95MB.
Comment 1 Aron Budea 2016-07-29 05:55:48 UTC
Reproduced in LibreOffice & 7. (opening original RTF in doesn't display logo)

The RTF jpegblip in the 93MB file mostly consists of FFFFFFFF..

Intersting observation:
Resizing JPEG in the document with mouse produces weird results. If I try to increase horizontal size to the left a bit, size increases to the right instead. If I increase it a lot to the left, the logo moves.
