Disabling all extensions does not fix the problem.

Enabled log-level=0 and got the following:

$ google-chrome --enable-logging --log-level=0
[20397:20397:1383124398002:ERROR:chrome/app/chrome_dll_main.cc(247)] GLib-GObject: instance of invalid non-instantiatable type `(null)'
Segmentation fault

Adding debug log.

Do you have crash reporting enabled?  If so, a crash id should be dumped, and if you give that to us, then we can look up what caused the crash.

My client_id appears to be B7776A6E-F752-1E5B-E46B-ACD5F961EE30.

I see crash_count: 0, but since I've enabled it I've gotten it to crash twice.

Seems to happen immediately after geolocation is finished.

I only see 2 browser crashes from your client id:

Are they the same? I can reproduce it a few more times if you'd like.

I'm guessing geolocation tries to initialize glib-dbus, which is crashing, possibly due to a race condition. Perhaps r50652 fixes this, or cause the crash to happen sooner?
