Bug#565245: epiphany-extensions causes epiphany to crash on startup

[David Weinehall]

Package: epiphany-extensions
Severity: grave
Version: 2.28.1-2

The latest combination of epiphany and epiphany-extensions
(2.29.5-1 and 2.28.1-2, respectively), causes epiphany to crash on
startup.  Since epiphany has no way command-line option for starting
without extensions enabled (at least none documented) the only way to
use epiphany is to uninstall epiphany-extensions, or to manually edit
the GConf settings for epiphany (which isn't something end users are
expected to do).

Disabling all extensions by using the GConf editor, then re-enabling
them one at a time, I managed to identify the tab-states extension as
the guilty party.

Rationale for severity: epiphany becomes impossible to start and thus
totally unusable.

The console output from a crashing epiphany follows below my signature.
