I've got the same bug.I'm stuck... Any help??
Try to:
- reload your saved file before accessing this part of the map (eventualy - I'm not sure it does something),
- click (left click) several times,
- also press the 'enter' key (i.e. z key) several times.
Finally, after several seconds (tens of seconds ?), I've been able to pass this step: AFAIR I've finally got something like '...' as a first message, then a few words still a few seconds after, and finally all the rest of the messages.
So, my advice would be: "keep trying".
