Verified the cause being ia32-libs containing a very old mesa snapshot
which is getting used on amd64 (which flash uses for the 32 bit plugin)
by testing the amd64 flash plugin (which worked) and then updating
ia32-libs and using the 32 bit flash plugin (which also worked). Mesa
7.9 did not contain functional sandybridge GL support and DRI was
disabled completely to work around it in maverick but it has been
reenabled in natty and is unfortunately using the old broken mesa 7.9
for 32 bit apps.
** Package changed: mesa (Ubuntu) => ia32-libs (Ubuntu)
** Changed in: ia32-libs (Ubuntu)
Status: Confirmed => Triaged
