Dear all,

With recent standalones (jan. 7, jan. 29 and march 2) I am experiencing trouble processing .tex-files that gave no problems in november (14-11).
For instance, when processing with "ConTeXt  ver: 2013.01.02 18:19 MKIV  fmt: 2013.1.7  int: english/english", the log file gives the following information: 
-------------------------------------------------------------------
! LuaTeX error [string "\directlua "]:1: invalid escape sequence near '\s'.

system          > tex > error on line 47 in file Chapter_4_S2MyBq-02-03-example.tex: LuaTeX error  ...
-------------------------------------------------------------------

and further on:
-----------------------------------------------------------------
45     \placeexample[here][ZarlConsCh38p188tot]{Zarlino\index[Zarlino]{Zarlino, Gioseffo}, Consonances ch.38, p.188}
46     {\startcombination[1*2]
47 >>  {\externalfigure[ZarlConsCh38p188fa]}{facsimile}
48     {\externalfigure[ZarlConsCh38p188fi]}{transcription}
49     \stopcombination}
----------------------------------------
The processing stops at line 47.
The log-file's last words are: "<inserted text> ...number \foundexternalfigure ; }"
I have no clue as to what to do with that information.

Just for the sake of completeness: In the setupfile "example" is defined:
\definefloat[example][examples]
\setupcaption[example][way=bychapter,prefix=yes,prefixsegments=chapter,location=top,number=yes,inbetween=\blank,bodyfont=10pt]
\setuplabeltext[en][Example=Ex. ]

As said, "ConTeXt  ver: 2012.11.14 11:37 MKIV  fmt: 2012.11.15  int: english/english" gives no problem at all.
Also, \placetable[here][tab:ref]{caption}} does not seem to trigger problems in recent versions.

Has something been changed in the commands for placing external figures since november?
What would I have to change, either in the setup or in the commands for placing the example?

Thanks in advance for any help.

Best regards,
Robert Blackstone
