Expected behavior
No crash

Desktop (please complete the following information):
Windows 0.1.6

Additional context
Once I was able to get Contents' default text pasted in today's journal file pressing crtl+z and ctrl+y randomly (Unable to reproduce again). I don't use Journal so I don't know how that corruption happened.
