[Bug 274661] [NEW] Firefox freezes with various Flash Uploaders from different web pages

[Pablo Olmos de Aguilera Corradini]

Public bug reported:

Binary package hint: flashplugin-nonfree

When you try to upload a file with a Flash uploader to various services
like http://www.picnik.com, http://www.vimeo.com or
http://www.mediafire.com. Firefox freezes and stop responding. To close
it I'd to kill the process.

Steps to reproduce the bug:

- Open Firefox
- Go to http://www.picnik.com
- Try to upload a photo
- Freeze

I'm using:

Description:	Ubuntu intrepid (development branch)
Release:	8.10
firefox-3.0 version 3.0.3+build1+nobinonly-0ubuntu1
flashplugin-nonfree version  10.0.1.218+10.0.0.525ubuntu1 (but it happened with the last package from Hardy too)

about:plugins in firefox shows:

    Nombre del fichero: libflashplayer.so
    Shockwave Flash 10.0.0 d525

I don't have installed libflashsupport.

I'd followed the procedures from:
https://wiki.ubuntu.com/MozillaTeam/Bugs?action=show&redirect=DebuggingFirefox
and I'm attaching the log.

I found some parts could be interesting so I'm going to paste it
directly here with two explications:
