[libreoffice-users] Question on Opening PDF files created by LibreOffice?

I've just had a strange issue with two PDF files created with Libre 
Office. 

If the file is created with the PDF/A-1a option the user with an 
Apple System gets an error and it will not option. If I create the file 
with the PDF/A-1a unchecked the file can be opened with the 
Apple. They can also see the document it they save it and use a 
preview option.

Strangly, I tried to open the same file with Safari on a Windows 
machine, and seem to get the exact same error.

When using Safari the open produces the following two 
messages.

First Message comes up.

The file you have opened complies with the PDF/A standard and 
has been opend read-only to prevent modifications.

Second Message comes up.

Adobe Reader
There was an error processing a page. Invalid Color Space.

If I open the file saved without the PDF/A-1a the first message 
also shows up, but the PDF file does open and display just fine.

Both files open fine on machines using mozilla on Windows and 
Linux, but not on Mac? 

So, this might be a MAC/Safari issue, but if it could be fixed that 
would be best.

Thanks.
