Workspace.registerOpener (/Applications/Atom.app/Contents/Resources/app.asar/src/workspace.js:1013:12)
Object.activate (/Users/Ryotaro/.atom/packages/web-view/lib/web.coffee:9:19)
Package.activateNow (/Applications/Atom.app/Contents/Resources/app.asar/src/package.js:238:19)
<unknown> (/Applications/Atom.app/Contents/Resources/app.asar/src/package.js:219:30)
Package.measure (/Applications/Atom.app/Contents/Resources/app.asar/src/package.js:163:15)
Package.activate (/Applications/Atom.app/Contents/Resources/app.asar/src/package.js:211:14)
