Thanks. At the moment I get exception when saving aproof that was started not via a .key file but by selecting a directory and choosing a proof obligation.

Steps to reproduce:

• File > Open:
  • Navigate to examples/firstTouch/06-BinarySearch
  • Select the src/ folder
• Run the proof
• Saving the completed proof results in the error message "No proof present"

Should be resolved. NPE during saving as the header variable is null, as these proofs are not obtained by reading a KeY-file.
