"R-Extension Issue with Package SQLDF and TCL/TK"

SQLDF does not work with RapidMiner and R extensions.

test <- rnorm(500)
sqldf("select * from test")
Error in structure(.External("dotTclObjv", objv, PACKAGE = "tcltk"), class = "tclObj") :
  [tcl] out of stack space (infinite loop?).

Suggestions?
