Comment 17 for bug 559855

This bug is related to a change made in vte in v 0.24.1 or 0.25; see Gnome bug #602596 [0]. The change is backported by Gentoo's vte-0.24.0 package (from the gnome overlay), so Gentoo users might be seeing it in that version as well.

The same problem manifests in Xfce's Terminal and is documented in Xfce bug #6423 [1]. I suggested some workarounds there.
