Crash on exit in Qt label update
I'm occasionally seeing a crash on exit in aevaCMB, but the call stack is pointing to smtk. It appears to be trying to update a label after the Qt object has been deleted or made invalid.
I think the crash happens when the operation tool parameters panel has focus when I exit.
smtk/extension/qt/qtReferenceItem.cxx:49
