Comment 3 for bug 71887

Some other software that breaks:

 -- Mathematica
 -- NX Server

This is what nxserver does with dash:

user@machine:~$ sudo /etc/init.d/nxserver stop
/etc/init.d/nxserver: 21: Syntax error: "(" unexpected

I really feel it is unfair to users not to give them an informed choice. For sure, it can be said that the bugs here lie with Mathematica and nxserver, not ubuntu, but the real-world environment of Ubuntu's users should be considered first.
