Floating table caption extends textwidth

["Michael Fuchs" <Michael.Fuchs@hiskp.uni-bonn.de>]

Hi!

I have problems creating a "multi-line" caption for a floating table.
If the caption is too long it will extend the text width. The following
example shows this problem on http://live.contextgarden.net/. 

I was able to find out, that this problem only appears if one of the 
variables "width" or "textwidth" in the "setuplayout" command were 
used to define the textwidth. 

Regards 

Michael





EXAMPLE:
--------------------------------------------

 \setuplayout[
        backspace=25mm, topspace=10mm, header=10mm, headerdistance=5mm,
        width=16cm,     % <-- COMMENT THIS TO SEE THE EX WORK
        height=fit,footer=10mm, footerdistance=5mm, bottom=5mm]

 \starttext

\placetable[here][tab:Referenz]
 {Zusammenfassung der Ereigniszahlen in Signal und Untergrund mit... 
  erfülltem $z$-Cut und einem über den Massenschnitt identifizierten
$\pi^0$.
     \nolist{Ereignisse werden in dem durch den $2 \sigma$-Massenschnitt
     vorgegebenen Intervall gezählt, das auch bei den endgültigen Schnitten
     zu Selektion verwendet wird.}
 }
