Not conciously, which should mean, not at all, on my system.

As I said, I updated siunitx via tlmgr. Could it be, that it updates 
other files as dependencies?

Lubuntu 12.04 with texlive 2011 from tug.org.

Yes, the same problem. (BTW: I copied this font to either 
/usr/share/fonts/opentype or 
texlive2011/texmf-dist/fonts/opentype/public. fc-list named it TG 
Pagella Math but I couldn't load it via \setmathfont{TG Pagella Math}. 
Only copying to the directory and loading it by filename worked.)

I don't.

Of course.

I hadn't tested it with lualatex. I did now and it has the same problems.

Thanks for your help.
