A widely used Bitcoin wallet service plans to issue refunds to people who saw their bitcoins stolen as a result of a weakness in its application. The issue came to light after one user reported 1.8 bitcoins — worth around US$218 as of Wednesday morning. The number of affected users is small, said an investor in the service, who said he expects to refund around 50 BTC or US$5,000. The problem is similar to one discovered earlier this month in some Bitcoin wallet programs running on Android.”]
