Summary: DRC crashes pcb

Initial Comment:
i am using the ubuntu lucid package (amd64) which is based on the 20091103 snapshot.
i had problems with the DRC throughout routing my first board. i think it started, when i inserted the first arc.
although it worked most of the times and crashes were not reproducible... now it does not.
the attached file seems to reproduce it very well (i hope its self contained, source looks like it...).
when i launch the DRC i can see it checking individual lines, but after a few hundred ms to a few seconds pcb crashes.

there were lots of fixed to arcs in bug report id:2942582 which are not included in my version afaik.
