Trying to add a new computer/code will crash aiida if the file is not saved

steps to reproduce, here i use vim

verdi computer setup

fill everything as prompted when asked to do so.
when comes to append extra lines, do not save just use :q that will generate the crash above.

this happens for both computer/code mainly due to assumption that a file will always exist to be appended

@alinelena Which AiiDA version are you using here? There was a similar issue recently, fixed in #4436. The fix should be in version 1.4.3.

Yes, this was fixed in PR #4436 which was released with 1.4.3
