Summary: studio hung eating CPU when I turned on tangent ducks
Initial Comment:
I had just used the 'draw' tool to draw a bline, then tidied if up with the
normal tool, with tangent ducks turned off to make the vertex ducks easier to
spot. Then I turned on the tangent ducks to tidy them up and synfig hung,
eating all available CPU.
Attaching to it with gdb shows it's here:

At this point no prompt came back, and the CPU went back up to 100%. It stayed
there while I composed this bug report, and shows no signs of stopping. I
tried re-attaching with a new gdb process, but couldn't.
