Crasher: Joining end nodes of two paths together

Summary:

I have two paths. When I select the end node of each and click the Join Selected Nodes button on the top toolbar, Inkscape crashes.

I opened the emergency save and tried again. It crashed again.

Steps to reproduce:

• open classic twills circles etc.svg in Inkscape
• switch to the node tool
• select the rightmost node in Path 76 and the leftmost node in Path 71 (both in Layer 1)
• click the Join Selected Nodes button in the top toolbar
• undo

What happened?

Inkscape crashed, made an emergency backup, and suggested I file a bug report if I could reproduce the behaviour. Which I can. Here's the backtrace from the second time it happened:

What should have happened?

It shouldn't have crashed. ;) (It should have joined the nodes together.)
