If you are here then it is because someone isn't doing sufficient error handling.
Generally this is a bug. Some non-mutually exclusive ideas of what happened:
If you're seeing this instead of a Server 500 error or similar, it is possible—perhaps even likely—that useful information is available in the server log but we cannot show you that because AJAXy nonsense is likely afoot.
Please go back somewhere and try something again, consult an oracle, make a small sacrifice, or otherwise help us fix this.
