[PD] Pd GUI freeze with error message(Tcl)

[Ivica Ico Bukvic]

I've seen these also happen when something tries to address a non-existent
widget (e.g. when it is being closed or something similar). There is an easy
way to prevent this from ever stopping GUI from working by encapsulating all
commands streaming from pd->gui with a simple catch{<command>}. This is what
in part pd-l2ork does and I cannot remember when was the last time I had a
problem like this.
