Initial Comment: Pd-0.43.1 ("extended-20120424") compiled 10:32:22 Apr 24 2012 on squeeze/sid Debian GNU/Linux AMD64

I'm getting this error while writing values to an array/graph with tabwrite:

(Tcl) UNHANDLED ERROR: wrong # coordinates: expected an even number, got 91 while executing ".xf25d70.c create line \ 24 330.000000 \ 26 330.000000 \ 28 330.000000 \ 30 330.000000 \ 32 330.000000 \ 34 330.000000 \ 36 330.000000 \ 38 330.000000..." ("uplevel" body line 3) invoked from within "uplevel #0 $cmds_from_pd"

I've attached a .pd patch that reproduces the error here directly after loading (loadbang is wired to start dsp and the patch).

I believe, TCL does not like getting these "numbers" on "create line":

... 115 -inf \ 117 -inf \ 119 -inf \ 121 -inf \ 123 -inf \ 125 -inf \ 127 -inf \ 129 -inf \ ...

If this is the case, and the Pd "backend" sends these "numbers" to the TCL frontend, and that is what is causing the problems, then I would expect either the frontend ignoring these numbers and assume some other kind of maximum. OR the backend prevents sending this in the first place. At least I would expect no TCL error, as these kinds of errors make the UI more or less unusable.
