Race condition in mailto-mutt

Binary package hint: mutt

How to reproduce: Either setup /usr/lib/mutt/mailto-mutt as the mailto: link handler in Firefox and click on a mailto: link, or run `/usr/lib/mutt/mailto-mutt "mailto: link contents"` in Bash in GNOME Terminal.

Result: Most of the time (more than 90%) a window pops up and disappears immediately. When running it in Bash/GNOME Terminal it returns exit code zero and no error message.

Cause: It looks like there's a race condition: x-terminal-emulator forks a GNOME Terminal so the `rm -f $TMPFILE` command two lines down gets executed before mutt has a chance to read it. As such, it will exit immediately.

Workaround: Add a line with `sleep 1` above the `rm -f $TMPFILE` line.

Suggestions:
1. Make sure the `rm` command is only run after mutt has actually finished (or at least has had time to read it. I don't know whether mutt clears up temp files passed with -i by default).
2. Try to retrieve the exit code of mutt itself for the `exit` statement. I guess this would necessitate a change in gnome-terminal, to return the exit code of the commend executed with -e.
