Steps to reproduce a crash (unclear to me though whether this is what happened to the reporter):
1) open 'todos.svg'
2) select the group of connectors for the bottom-left diagram
(note: only one of them initially appears to connect two of the circles, the others have zero-length at the SVG origin -> this is tracked already in other reports)
3) ungroup it
(connectors are now rendered at expected positions)
4) drag a selection frame around the bottom-left diagram
5) group the selection
-> crash (see attached backtrace from r11513, OS X 10.7.4, 64bit).
