Package: epiphany-browser
Version: 2.30.2-1
Severity: normal

i just found a way to reproduce the "crashes when going back" problem on
my system:

* go to http://en.wikibooks.org/wiki/LaTeX/Packages/Listings
* scroll to the bottom by hitting the "end" key
* click the link to link "A quick example can be found *here*" to
  http://franz.kollmann.in/latex/latex.html#code
* wait for the page to load
* go back using the "back" hardware key
* epiphany segfaults

i tried the same thing on /usr/lib/webkit-1.0-2/libexec/GtkLauncher,
which didn't crash.

backtrace looks like this:

Program received signal SIGSEGV, Segmentation fault.
