[jjdredd]

Looks like process receives SIGPIPE when trying to write to stdout. Usually this happens the second time when I click on "preferences".

[jjdredd]

I've managed to work around this by ignoring the SIGPIPE, but I still don't know why this bug appears.

[jjdredd]

Using option --no-output-redirect seems to fix the issue.

[trufae]

Is this related to the empty project file issue?

[jjdredd]

No, this is a separate issue.

[trufae]

Should be fixed now
