Problems opening matlab from a remote shell from Ubuntu 14.04.

I've upgraded from Ubuntu 12.04 to 14.04, and this has created a problem which I didn't have with Ubuntu 12.04

when I open a remote shell with the command

ssh -YC <myIp> "xterm bash"

and then start matlab with the command

matlab -nosplash -nodisplay

two bad things happen. First, on startup I get the warnings:

libGL error: failed to authenticate magic 393
libGL error: failed to load driver: i965

Second, matlab takes forever to start.

running the profiler, the delays seem to be caused by the processes run and various forms of connector, which take much longer than when I open matlab locally. Profiler output is attached.

I have exactly the same problem if I run ssh -XC rather than -YC, but neither problem occurs if I simply open a remote connection with ssh myIp

Any advice would be most appreciated!

Opening matlab with the -nojvm flag fixed this problem.
