I can reproduce it with 5.3.7.2 (linux opensuse). 

Opening the above image with gimp, converting it to RGB (Bild -> Modus -> RGB),
insert it to the above test document again, the pdf will be fine. The same with
another image  which was also a company logo in CMYK as described in comment 9.
Would be great to get this fixed.

I get this bug in 5.4.5 even with resolution reduced.
I have to ensure I check my PDFs and if I find a problem convert the offending
image to RGB.

I can reproduce this bug everytime in any LibreOffice application (Calc,
Writer, Impress) in 5.4.x and 6.0.x version if I select Lossless compression in
the export to PDF dialogue. If I check Reduce image resolution then the images
are rendered correctly.

This is the image I used:

I have just noticed this issue in 5.2. Always reproducible.
I feel it started about the same time as bug 104479 so may be related to the
patch that caused that.

--- Comment #16 from Aron Budea  ---
So the underlying issue isn't created by the commit identified in comment 8, it
just makes the issue occur more frequently. If the original JPGs are preserved
and they are CMYK (that's the likely cause), this bug happens.

In fact, the bug can be reproduced by following steps even in 3.3.0:
- Open / create a document with such a JPG included,
- Select File -> Export as PDF...,
- Select Lossless compression, uncheck Reduce image resolution, and click
Export.

With these steps, Vedran's image shows similar distortion/decolorization as the
reporter's (so probably some settings were different from default).

The regression part is what's been reported in bug 105954, fixing that should
reduce the occurrence of this issue. Adjusting keywords and version field.

What were the steps you followed? I inserted it in a document, then exported
the document to PDF, but the image looked the same (LO 5.3.0.3 / Windows 7).
Maybe you did something differently?
