[R] Odd crash with tcl/tk

[Lars Dalby]

Hi

@ Andrew: Did you get this problem solved?
I am having similar problems and have tried to work around it using
options(gsubfn.engine = "R") as suggested by Gabor.
However, this don't solve on my machine. R just freezes up trying to
execute read.csv.sql()

On OSX 10.6.4, R 2.11.1 (2010-05-31) 64bit

Any help is much appreciated!

Lars
