that's not a (shipped) included app in elive, cannot fix 
, there's too many packages on debian that should be fixed otherwise lol
make a look to the file /usr/share/applications/guake.desktop (or similar), you would see the issue on the Exec= entry here, this is bad made, it should include an entry like:
Terminal=true
in case that requires a terminal, but running it that way is not correct and very hacky
so you should instead report the bug to the author of the package (if ships with a .desktop file) or to the debian maintainer of that package
there's a big documentation called .c files (ok joking 
, but is useful most of the times)
check my just other-commented thread, maybe there's the answer (and remember to purge caches if no effect)
