Gmail users have reported a strange bug in the autocomplete feature for the recipient field. The world’s most used email service is apparently now suggesting names that are least used, instead of the most common names used. It doesn’t break the service, but it does open the problem of sending email to the wrong person many times over.
The issue seems to have appeared several days ago, with users complaining about accidentally sending messages to people who are not the intended recipient. This current bug favours email addresses used once over those used multiple times, meaning that it is most likely to autocomplete the names to someone most users barely communicate with.
We're aware of an issue with Gmail and auto-complete and are currently investigating. Apologies for any inconvenience.

Google itself has taken to Twitter to announce that it is aware of the issue and are investigating it. There should be a fix coming soon, and until then Gmail users are advised to double-check their recipients before hitting the send button.
