dpkg-deb error when using multi-gnome-terminal

[Florentin Ionescu <florentin_ionescu@comcast.net>]

I encounter a weired error while trying to install (dia) - if command is ran
multi-gnome-terminal fails like this :
dpkg: error processing /var/cache/apt/archives/dia-common_0.91-10.1_i386.deb
...
dpkg: error processing /var/cache/apt/archives/dia-common_0.91-10.1_i386.deb
(--unpack):
 subprocess dpkg-deb --control returned error exit status 2
 dpkg-deb: subprocess tar killed by signal (Aborted)
...

If the same command, is ran in xterm is completed successfully - does anybody
knows why ?

Thank you,
Florentin.
