Strange behaviour of width parameter in \setuplayout (Was: 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 defined text width.
The following example shows this problem.

I was able to find out, that this problem only appears if the
variables "width" in the "setuplayout" command was used to define
the textwidth. If you comment the line containing the "width"
parameter (see comment in example) the caption will not extend
the table.

Example:
--------------

 \setuppapersize[A4][A4]
 \setuplayout[
        backspace=25mm, cutspace=25mm,
        width=16cm,     % <-- COMMENT THIS TO SEE THE EXAMPLE WORK
        footer=10mm, footerdistance=5mm, bottom=5mm]

 \starttext

 \placetable[here][tab:Referenz]
 { \input tufte }
 {
 \setupTABLE[x][1][width=4cm, align=middle]
 \setupTABLE[x][2,3,4,5][width=3cm, align=middle]
 \bTABLE
    \bTR
        \bTH Anzahl \eTH
        \bTH Daten \eTH
        \bTH MC \eTH
        \bTH Daten \eTH
        \bTH MC \eTH
    \eTR
 \eTABLE
 }
