[Bug 1477760] [NEW] Crash when clicking a link in desktop G+

  Thread Previous • Date Previous • • Thread Next 
Public bug reported:

There is an oxide crash when clicking on a link when in g+, any link
that should popup externally seems to trigger it.

The responsible is a NULL entry pointer (NavigationEntry) as the
LoadSucceeded call is being issued. The URL browsed to is a transient
"about:blank" right before the actual target url is hit.

Here is a small stacktrace:
