Please add a confirmation dialog box to the "Assign to Me" button on the Operations bar. In general, users are finding it too easy to accidentally assign something to themselves, particularly since the button also has a keyboard shortcut. If someone accidentally presses "i" while on a view issue screen, they become responsible for the issue.

Setting Affects Version to 5.0.5, since that's the JIRA version I currently have deployed, but this really affects all JIRA versions back to when the Operations bar was added (and possibly earlier).
