Yep it's the same for me in Edgy, same debugging output at the console. It didn't happen in Dapper so this seems to be a regression. Interestingly it only happens on the machine I've newly built with Edgy final release Live CD - the ones I've kept up to date having installed from the Edgy Beta live cd seem to cope with Flash fine.
export XLIB_SKIP_ARGB_VISUALS=1 fixes it as it did in Breezy. This is the same with both the flashplugin-nonfree and the self- installed copy of Flash 9 beta as Aaron Whitehouse pointed out. -- Flash plugin problem with ARGB visuals causes crash https://launchpad.net/bugs/14911 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
