Hallo,
I got a strange error after running LyX
and trying to export it as pdflatex:
pdfTeX error (ext4): \pdendflink ended up in different nesting level than \pd
which I traced to
Lichtflüssen zwischen 0.5
und 75\thinspace\mathrm{\mu mol/m^{2}/s}
(siehe Abbildung [fig:Licht-Sharma]). Bei Flüssen bis zu
20\mathrm{\thinspace\mu mol/m^{2}/s}
änderte sich die Periode nicht
If I take the
20\mathrm{\thinspace\mu mol/m^{2}/s}
out, the error is gone and the pdf output works.
Now if I copy
75\thinspace\mathrm{\mu mol/m^{2}/s}
to the place of
20\mathrm{\thinspace\mu mol/m^{2}/s}
(replacing it)
I get again the error meaning that it is not the sequence
\thinspace\mathrm
respectively
\mathrm{\thinspace
which caused the error
The strangest finding is, if I put the
Bibtex generated Bibliography
mark at the end of my Koma book (twosided, twocolumn)
in a lyx note thus commenting it out the error vanishs.
This was in fact the way I started the search for the error, because I
thought removing the Bibliography entrance is a fast and effective way to
find out whether a reference is causing the problem.

In the meantime I have experimented a bit more stripping my document to a
few lines and it seems that the upgreek is causing the trouble.

)
but why does the erro occur only if I use the math expression twice?
