Lars, do you know who could take a look at this crash ?

Comment 2

[Lars T Hansen [:lth]]

I should probably look at that.  This is similar to the failure I had yesterday on check-in; there seem to be some assumptions in the locking code that are just wrong, and I just happened to stumble over it.  Has this been going on for a while?

(I may push this before review, depending on turnaround time, if the Sheriff approves of it as a quickfix.)
