Ha. Looks like that #rehash does better fit in Object >> #readDataFrom:size:. See Kernel-mt.1526 and System-mt.1424. SqueakMap Catalog should update again fine in Trunk again. :-)

So, we probably should not call #rehash on objects that are incomplete there due to cycle detection. Hmm...

The dictionary in question is the "objects" instVar for the central instance of SMSqueakMap. it interesting thing is that it passes twice through SmartRefStream >> #next. The first time with an invalid array and the second time complete and re-hash-able. Hmm...

The issue appears to be that deep in the process a Dictionary exists that has a tally of 4162 but an array of nil. Which doesn't seem quite proper somehow.
The starting point is SMLoaderPlus>loadUpdates but a long way later we get to SmartRefStream>>#readInstanceSize:clsname:refPosn: with a refPosn of 1270478. A couple of methods later we try to rehash the Dictionary
This can never end well.
There's no way I have time to do anything much with this, so volunteers needed...
