I am not sure yet if it is directly related to gxine.
When visiting various multimedia sites, the gxine plugin takes over.
It appears to be for different multimedia formats.
Sometimes firefox exits immediately and sometimes later when gxine is closed.
Firefox closes with "Segmentation fault".
So I enabled core dump and back traced in gdb:

Previous frame identical to this frame (corrupt stack?)

I can reproduce a "Segmentation fault" at many websites, such as
http://movies.guide.real.com/movie/2005/mr_and_mrs_smith/trailer.html?autostart=true

When running firefox through strace, it does not seg fault though so I can not
track down with strace.




Reproducible: Always

Steps to Reproduce:
1. Visit some multimedia site that uses gxine plugin.
2.
3.

Actual Results:  
gxine may or may not play multimedia.
firefox may die with Segmentation fault before or after multimedia is played.

Expected Results:  
firefox should not have segmentation fault. If a plugin causes problem, firefox
should complain appropriately.

It may be that this problem is caused by something else, but this software crash
is only noticed in firefox.

gxine works great as standalone.

This is an automated message, with ID "auto-resolve01".

This bug has had no comments for a long time. Statistically, we have found that
bug reports that have not been confirmed by a second user after three months are
highly unlikely to be the source of a fix to the code.

While your input is very important to us, our resources are limited and so we
are asking for your help in focussing our efforts. If you can still reproduce
this problem in the latest version of the product (see below for how to obtain a
copy) or, for feature requests, if it's not present in the latest version and
you still believe we should implement it, please visit the URL of this bug
(given at the top of this mail) and add a comment to that effect, giving more
reproduction information if you have it.

If it is not a problem any longer, you need take no action. If this bug is not
changed in any way in the next two weeks, it will be automatically resolved.
Thank you for your help in this matter.
