Bug#971345: WebKitNetworkProcess: random crashes (SIGABRT)

Paul Wise pabs at debian.org

Package: libwebkit2gtk-4.0-37
Version: 2.30.1-1
Severity: normal
File: /usr/lib/x86_64-linux-gnu/webkit2gtk-4.0/WebKitNetworkProcess
Usertags: crash

I got seven random WebKitNetworkProcess crashes (SIGABRT) at around the
same time. I have no idea how to reproduce these crashes. All of the
crashes have a short backtrace like the one below. If the short
backtrace below and the full backtraces attached aren't helpful, then
please close this bug report.
