Summary: Another "Tcl Invalid Command Name error" and frozen GOP gui 

Initial Comment:
Pd-extended 0.43.4
Linux Ubuntu Lucid 10.04
built-in sound

This error is demonstrated with a simple patch (attached) that reproduces it.
It seems related to the <Hide> flag for a 2nd level nested GOP patch.

it's been tested on MacOSX <10.6 and Ubuntu 12, 10

how to reproduce:

- launch MAIN-graph-bug.pd
- click the bang to open a subpatch (if it doesn't at startup)
- close the subpatch
- close MAIN-graph-bug.pd

at this point Pd throws the error as below. Only the GUI freezes, the patch is  unusable and have to kill it, by closing pd.

\\\\\\\\\\\\
(Tcl) INVALID COMMAND NAME: invalid command name ".x996ebd0.c"
while executing
".x996ebd0.c delete graph996f4b0i0"
 ("uplevel" body line 1)
 invoked from within
"uplevel #0 $cmds_from_pd"
\\\\\\\\\\\\


How to avoid it:

- launch MAIN-graph-bug.pd
- click the bang to open a subpatch (if it doesn't at startup)
- open the subpatch
- open the further subpatch <anlz.scope~>
- flag hide object name and argument
- save
-close pd
- restart the patch and the error disappear
