[tmodes <1048799@xxxxxxxxxxxxxxxxxx>]

That's already fixed in the repository. This is related to a change inside boost.
Update Hugin to 2012.0 (we are currently at RC1, no final yet.)
Or downgrade boost to <1.47 (e.g. 1.46.1)

** Changed in: hugin
       Status: New => Fix Released

Title:
  nona raises  a segmentation fault at the very first call

Status in Hugin - Panorama Tools GUI:
  Fix Released

Bug description:
  I can see the panorama preview, but when I want to assemble the
  panorama, nona raises a segmentation fault.

  Hugin Version: 2011.0.0.0f9fdaf56720 setuped on a Gentoo box, compiled with gcc-4.5.4, glibc version = glibc-2.15-r2, kernel version = 3.2.12-gentoo x86_64
  boost version = boost-1.49.0-r1

  Here are attached or displayed directly in the bug description : 
  - Hugin crash report
  - hugin PTO file used by nano command
  - hugin MAKE file generated before nona call
  - gdb ouput when calling nona manually and the backtrace output.

  If anything else is needed, please tell me : I'm not sure what to post
  here...
