I use ParseUI to handle signup. I have a couple of users experiencing this crash when signing up for an account:
java.lang.IllegalArgumentException: Cannot sign up a user that is already signing up.

According to the users, it crashes right away when clicking the sign up button, instead of waiting for a few seconds of timeout. There is no duplicate account in the backend, they are signing up new.
One user has a custom ROM. Another user rooted his device before. But I am not sure that matters.
I cannot reproduce the problem. Most users do not experience this problem. I would appreciate your insights. Thanks.
