Package: libwebkit-1.0-2 Version: 1.2.1-2 Severity: normal i found a problem with epiphany that also shows up in the libwebkit reference browser; it occurs when browsing to http://design.canonical.com/2010/04/notification-area/ and causes the browser to become unresponsive, eating 100% cpu. when interrupted, gdb is usually in FEGaussianBlur.cpp.
here is the backtrace, just let me know if something is missing. $ gdb /usr/lib/webkit-1.0-2/libexec/GtkLauncher [...] (gdb) run http://design.canonical.com/2010/04/notification-area/ [...] [lots of
