Details:

Debian Sid/unstable is running with the following.

    browser-plugin-gnash                          0.8.11~git20120629-1

Using Midori and opening several phoronix.com pages in tabs which use flash
advertisement a lot, Midori crashes.

    midori[8497]: segfault at c7ebc150 ip a85d98d3 sp bfebc100 error 7 in
libgnashplugin.so[a85b5000+47000]

The was able to capture a core dump and running GDB on it(?) I got the
following back trace.

Backtrace stopped: previous frame inner to this frame (corrupt stack?)

Even *if* Midori is doing something wrong here the library should never
segfault!

Please tell me if you need more information.
