The trigger of the bug seems to have been fixed in Firefox 18.0, but it's still present in Thunderbird 17.0.2:
xwininfo -size for Firefox 18.0 gives: Program supplied maximum size: 32767 by 32767
xwininfo -size for Thunderbird 17.0.2 gives: Program supplied maximum size: 1073741824 by 1073741824
Behaviour of different sawfish versions in precise:
sawfish 1:1.5.3-2build1: Firefox: GOOD (can be resized). Thunderbird: BAD (can't be resized).
sawfish 1:1.5.3-2ubuntu1: Firefox: GOOD (can be resized). Thunderbird: GOOD (can be resized). No side effects observed.
So, the updated sawfish package fixes the bug properly.
I have not tested it in quantal.
