Thanks Hans for your reply. My version up to 15 minutes ago was: 2011.02.14 19:48. Now it is : 2011.02.25. In the meantime I updated the minimals and it does indeed use the fallback. Only then I realized, that in the type-otf.mkiv the typefacedefinition for math of libertine is commented out... Willi On 9 Mar 2011, at 14:24, Hans Hagen wrote:

Hi all,

I just installed the libertine fonts. They work but what should I do with this error?

! Math error: parameter \Umathquad\displaystyle is not set.

how old is your context? recent version sshould check for math being undefined and load lm as fallback
