Bug 101603 – ASSERTION FAILED with gstreamer-1.0

• Status: RESOLVED
• Resolution: DUPLICATE
• Component: WebKitGTK

[ChangSeok Oh]

The build command is ../../autogen.sh --prefix=/usr/local --enable-debug --enable-webgl --disable-egl --with-gstreamer=1.0
And then visit  here ./Programs/GtkLauncher http://www.w3.org/2010/05/video/mediaevents.html

Both WK1 and 2 have a same issue.

Backtrace:

Program received signal SIGSEGV, Segmentation fault.
