PDF file size bigger in 5.2.4

Hi.
I just got an update through to LO 5.2.4. I think this has caused my PDF output file to grow from 6 MB to 10.5MB with an odt of ~22MB.
5.1.6 produces the 6MB file, I am pretty sure 5.2.3.3 produced a 6MB file. All settings the same as far as I can tell.

Can't see a bug listed, wondered if anyone else noticed this.
Using Opensuse 13.2

I guess with the same settings, specially those in relation with images size.

The export button use the settings on Menu/File/Export as pdf.

Copy to list.
I have now performed more investigation into this unresolved bug, the information may be useful to those producing PDFs of documents for distribution where size is of some importance, it has forced us back to the 5.0 series for our company. The effect is more noticeable the more images are in the odt. The odt file producing these PDFs is about 22MB

The bug is the same on Win 7, 32 bit and opensuse x64.
Sizes on the PDF produced from the same document for various versions of LO follows.
LO 5.0.6.3. PDF 2.5MB
LO 5.1.6.2.0+ PDF 6.3MB
LO 5.2.4.1 PDF 11MB
