Thanks for taking the time to report this bug and helping to make Ubuntu better. We appreciate the difficulties you are facing, but this appears to be a "regular" (non-security) bug. I have unmarked it as a security issue since this bug does not show evidence of allowing attackers to cross privilege boundaries nor directly cause loss of data/privacy. Please feel free to report any other bugs you may find.

I am a fish developer. What version of fish are you using? What does `locale` report? Steps to reproduce? Can you set `ulimit -c unlimited` and reproduce the problem to get a core dump for analysis? Note that we recently made several changes to avoid mixing narrow and wide stdio calls which can lead to unpredictable behavior so the fish version you're using is important. Also, since it is more likely this is a fish bug than a Ubuntu specific bug it will probably be more fruitful to open an issue against the fish project: https://github.com/fish-shell/fish-shell/issues/new

Status changed to 'Confirmed' because the bug affects multiple users.

I think I'm affected by the same bug. The weird thing is: I think I only get this when starting Atom but I'm not sure.

It sure doesn't crash one of the shells I'm actively using. I just get the "an application on your system has crashed" dialog.
