regression - ia32-libs gtk does not find 32bit engines

seems that this regression was introduced on gtk side: latest upload builds with --host=i686... and not i486; the fix on ia32-libs side is trivial and involves just shipping the proper link.

adding gtk+2.0 ... leaving importance untouched until we know about the impact

ia32-libs_2.7ubuntu6_source.changes uploaded to jaunty

This bug was fixed in the package ia32-libs - 2.7ubuntu6

---------------
ia32-libs (2.7ubuntu6) jaunty; urgency=low

  * debian/rules: gtk+2.0 has a bug in jaunty that builds it with
    --host=i686-pc-linux-gnu; to mitigate this we ship a
    /usr/lib/gtk-2.0/2.10.0/i686-pc-linux-gnu link instead of the i486 one
    previously used; this change should be reverted in karmic (LP: #364074)

workaround has landed in ia32-libs; untargetting gtk; obviously will be fixed in karmic still.

I am still seeing this with a brand new install of 9.04 yesterday and then all updates applied as of this morning.
$ ./acroread

modules are a separate issue that isnt covered by this regression bug
... modules never worked properly; if you open a new bug i would be
happy to drive for a fix for that.

I updated to 9.04 this morning. I've 2.7ubuntu6 of ia32-libs installed but receive this error when starting firefox:

Gtk-Message: Failed to load module "canberra-gtk-module": /usr/lib/gtk-2.0/modules/libcanberra-gtk-module.so: wrong ELF class: ELFCLASS64
*** stack smashing detected ***: /usr/lib/nspluginwrapper/i386/linux/npviewer.bin terminated

Is this at all related to https://bugs.launchpad.net/ubuntu/+source/flashplugin-nonfree/+bug/369123 ?

The 'modules' bug is there: https://bugs.launchpad.net/ubuntu/+source/ia32-libs/+bug/369498

Fixed in karmic some time ago:

gtk+2.0 (2.16.1-0ubuntu3) karmic; urgency=low

  * Add missing backslash after --enable-print-backend which cause the --host
    and --build args to be ignored and hence the wrong triplet to be used.

I have a fresh installation of Karmic and libgtk2.0 2.17.11-1ubuntu1 and I still get:

Getting this error in Natty with Firefox 4.0b10 (from repos). Is this actually a bug?
