Ubuntu 9.04 Renoise Segfaults on dual screen

Downloaded the demo of renoise to play around with, installation went fine, then it simply refuses to run.

Output:-

  
cottandr@AndyPC:~$ renoise  
Segmentation fault  
  

I am running 32bit Ubuntu 9.04, on an AMD athalon 3400+ (which does have SSE), and using nvidia twinview for dual monitors.

Renoise does not start to load any modules, and does not output any log files.

Any Ideas?

Thanks.

this is a known and currently unresolved issue. see here

I think this may be a different issue, as running under gdb or strace, renoise runs with no errors, but running outside it segfaults immediately
