>Description:
xfce4-terminal, and most likely gnome-terminal, too, suffer from a bug in 
x11/vte. This bug is that the "Alt"-key is not mapped/processed properly.
It's a known bug for some years now, and has been fixed in version 0.28.2. 
pkgsrc-current however is using 0.28.1 with lots of patches.

>How-To-Repeat:
Install an xfce- or gnome-terminal, x11/vte will be installed as a dependency, 
and do something that would require the alt-key on the shell, like typing this:

# test case

and then hitting alt-backspace.

Expected behavior would be that "case" gets deleted.

Real behavior however is that "e" gets deleted.
>Fix:
To solve this problem quickly, I applied this patch [1] I found in this 
bug-report [2] to our version. After building and updating vte, the problem 
with the "Alt"-Key was gone, and the terminal is behaving as it would be 
expected again.

The patch doesn't need much changes, only the file-paths have to be adjusted.
