Unfortunately, this is hard to debug since the webapps packages are in a PPA and the Apport retracer won't retrace PPA packages.
If this crash happens again, please follow the steps at https://wiki.ubuntu.com/DebuggingProgramCrash in order to generate a stacktrace which you can attach to this report as it would help us in understanding this issue. I'm marking this Incomplete until then, and deleting the CoreDump for privacy reasons.
