It's a Tcl stack trace. Swarm widgets have funny names like
  .w<Class>@<address>
so
  address@hidden@address@hidden@0x401ec708
is an entry widget, inside a frame, inside a ClassDisplayWidget (part
of probe), inside a toplevel Frame.

I think Tcl has an error function that's called, but I don't know
offhand what it is. The Tcl interpreter object in Swarm has a debug
method, if you call
  [globalTkInterp setEvalDebugPrint: 1] 
it will cause all strings to be printed out before they go to the Tcl
interpreter. This lets you debug just the Tcl code: I've debugged
things by cutting and pasting into a wish and seeing what's breaking,
but it's a pain.


I can't really tell what's going on looking at that tcl trace. There's
some weird string
  8@"cell"
that seems to be causing trouble. It looks like a Probe widget is
trying to display this as the value for a slot on on object, and
that's breaking Tcl somewhere (probably because it's not quoted right,
yay Tcl!). Can you show me the class you're probing? Do you know where
the 8@ could be coming from?
