chromium-browser crashed with SIGSEGV in content::NPObjectProxy::NPInvokePrivate()

[Logan Rosen]

Although apport wanted to file this bug against chromium-browser, I changed the affected package to unity-chromium-extension, as it relates to that specific extension.

I received a "Unity WebApps plugin has crashed" message while browsing in Chromium, and then apport caught the crash.

Status changed to 'Confirmed' because the bug affects multiple users.

Closing now as this report wasn’t investigated timely and is now too old to be meaningful.
Please do not hesitate to report crashes occurring with recent releases of chromium-browser, they will hopefully be investigated and acted upon in a more timely manner.
