from gnome-terminal 2.4.x (and perhaps before) to 2.8.x, i had a bug with gnome-terminal, which comes from a bug in vte it is fully explained there : http://bugzilla.gnome.org/show_bug.cgi?id=122150 a patch is also available at the same place it seems that vte is quite unmaintained and this patch won't make it upstream for a long time. it has already been applied in Fedora and perhaps all debian based distros. Reproducible: Always Steps to Reproduce: 1. 2. 3.
2.7.3 atleast has this problem, and seems to be the last version that is not masked.
added to vte-0.11.11-r3 . I can't rep the problem so I'm going to assume this fixes it.
