[webkit-dev] SIGSEGV possibly (?) due to libwebkitgtk (backtrace included)

[Scott Kostyshak]

Dear all,

I am getting a SIGSEGV from a package that depends on
libwebkitgtk-3.0-0, gnome-web-photo (note that I am on Ubuntu 16.04).

The following command is what gives me the SIGSEGV:
gnome-web-photo "http://www.nba.com" "gwp_test.png"

it only happens with that website.

Here is the backtrace I have:

Core was generated by `gnome-web-photo http://www.nba.com gwp_test.png'.
Program terminated with signal SIGSEGV, Segmentation fault.
