In some cases, I don't immediately see a crash. But if I try a second time, I get a seg-fault for the text command. Both back-traces are attached.

I made to (trivial?) changes to text objects in the last two days.

I don't see how these could be responsible, but I hadn't seen this before, so they may be related.

Any ideas / insight?
