Hi brecht,
here is some more information....

undo steps set to 32{F32136}
blender crashes when doing an undo 'ctrl & z'... This happens shortly after linking in an object, making it local ,moving it around, then pressing undoto Crash making linked objects local and undoI can confirm the crash with the above steps, linking in all objects in this file.
@brecht, i couldn't really reproduce the crash. Do have:
messages in the console after the undo tho. Will have a look into this issue, but wouldn't mind having some details about crash..
cu->bevobj->data
and sobevcu
is NULL. It's easy to add a NULL check but that doesn't seem like the right solution.It should be possible to reproduce this if you follow these steps:
@brecht, managed to reproduce now. Checking for NULL is not the right solution at all, we need to understand why object data is got lost.
@brecht, the issue is actually caused by linked curve pointing to a local object which screws up the file loading. As far as i can tell it's not really supported situation so guess proper solution would be to disallow making IDs local if they're used by other datablocks?
Right, either that or making the other datablocks local automatically, but to me it seems better to refuse and let the user then use Selected Objects & Data. So yes, I think we should disallow it.
