Might actually be caused by memory crash on the background, while you still have 5-10 seconds to open a dialog and click the button: #1262

Please report after upgrading to 31.0.5 (planned for next week), if this issue is solved;
Or open Devtools -> Network and Console tabs, then navigate to Logging -> see if there are any errors reporting when you clicking the button
