Yes, it works (at least in a footnote I reproduced the error and it
disappears with the git version)
Just for the record, it also solves another problem I had with \vec:

./3-feshbach.tex:13: Undefined control sequence.
<argument> \l_um_growing_accents_bool

l.13 \[e^{i \vec

I had reported this to Will some time ago but he could not reproduce it.
However, with the new version of unicode-math, it is gone.
So I hope to see it on TLcontrib soon ;)

No Cambria on my machine right now, sorry …

Thank you very much for the fast response and bug fix!
