Sorry, I didn’t see your point before, but bugs should be reported on launchpad.net. The following will provide more detail on reporting bugs https://help.ubuntu.com/community/ReportingBugs
I’d suggest using the
ubuntu-bug <package> command to file the bug, and I suspect
gnome-terminal is the wrong package, but another user of this site may provide a better package to file against, or you could use
gnome-terminal & a bug-squad member will likely correct it for you after filing.
A wrongly filed bug is still better than none at all, and thank you for trying to file, and making Ubuntu better!
