Copying a global variable and pasting 2x hangs app

I am able to reproduce this bug in KWGT 3.52

  1. Create a shape object
  2. Create a global variable (anchor) name it pos1
  3. Add description
  4. Copy and paste the variable once (it adds pos12
  5. Tap on paste a second time and the app hanges
  6. The paste button shows it being pressed but there is no way to interact with KWGT anymore

This is a nasty bug because it erases your progress.
