[pstricks] uput and \SpecialCoor

[Juergen Rose]

If I use the following code, it works:

\begin{pspicture}[showgrid=true](\xpsmin,\ypsmin)(\xpsmax,\ypsmax)
  \psaxes[]{->}(0,0)(-0.3,-0.3)(\xmax,\ymax)

  \psdot[linecolor=cyan](! 2 45 cos mul 2 45 sin mul)

  \pstGeonode(\yCthree,\zCthree){C_3}(\yCfour,\zCfour){C_4}
  \pstGeonode[PointName={}](\yCfourProj,\zCfourProj){C4P}
  \pstGeonode[PosAngle=180](\yA,\zA){A}

  \ncline{C_4}{A}
  \ncline{A}{C_3}
  \ncline{C_3}{C_4}

  \ncline{C_4}{C4P}

  \rput(! 2 1.4 mul 1.8){$t$}
\end{pspicture}

If I replace the last rput statement with a uput statement, it fails
with:

...
( FP-UPN ( FP-MUL ) ( FP-ADD ) )
! Use of \uput at ii doesn't match its definition.
l.53   \uput(!
               2 1.4 mul 1.8t$}
? 

Is this intentional or do I make something wrong?

In the attachment there is a working example main_0_article.tex with
rput and a failing example main_1_article.tex.
