64 bit Thunar 'Send to mail recipient' fails, needs i386 library

Running 64-bit Xubuntu 12.04 alpha 2 in a Virtualbox 4.1.8 machine.
Thunar 1.2.3-2build1

Choosing a file to send from Thunar to a mail recipient using the context menu.
Get the error box :
Failed to execute child process "/usr/lib/i386-linux-gnu/Thunar/thunar-sendto-email" (No such file or directory).

Executing a 'locate thunar-sendto-email', we find that the program is in /usr/lib/x86_64-linux-gnu/Thunar/

So Thunar is not looking in the right directory.

Workaround: sudo ln -s /usr/lib/x86_64-linux-gnu /usr/lib/i386-linux-gnu
Works perfectly to fool the faulty file manager into finding the tool.

Similar to the bug described at ubuntuforums.org: http://ubuntuforums.org/showthread.php?t=1878018 although this seems to have been fixed in the latest Xfce packaged with xubuntu 12.04
