aliases not working

I guess this is a bit of a longshot. When creating a room with the @dig command it is failing on the semicolon seperator for the aliases. I show an example below.

@dig My Room = south;s, north;n

This fails. It will do south then fail all the others, but this one without the semicolon works.

@dig My Room = south, north

The use of aliases is pretty much a requirement so right now it's a show stopper.
Any ideas anyone?

I'm using linux ubuntu 12.04 (precise)

Thanks pete

[edit] its the same with @open also

I found the problem. The answer was here.

It was my client messing things up, (mudlet).
When I logged in using CLI the problem was resolved so I now have to find the cause in mudlet.

Thanks pete
