tkinter: setvar() passes AsObj's NULL to Tcl when the value's __str__ raises #161388
Description
Bug report
Summary
setvar() with three arguments crashes the interpreter with SIGSEGV if the value's __str__ raises.
Expected: the exception from __str__ should propagate, as it does from setvar(name, value).
