Well... Your Issue seems a bit different. It seems you have done Another quest, so it skipped the previous quest for Julie.
If you can replay, then try replaying that quest and reply to her before new messages appear.
I'll try starting a new game to recreate the problem. But i don't think it was due to another quest. When I couldn't reply to the message I just kept playing and eventually i got to a point where she messaged me further as you see in the screen shot. It wasn't taken when i encountered the problem. It's happened in both of my playthroughs so far
I was able to recreate it rushing straight through her story line. Received this error.

I'm sorry, but an uncaught exception occurred.
