I think this is a dupe of a fixed positioning crasher

Most likely a dup of bug 108940. Try pulling from the trunk and rebuilding ... I checked in a fix to 108940 a few hours ago.

> Try pulling from the trunk and rebuilding ... I checked > in a fix to 108940 a few hours ago. I tried a just completed trunk build and it does not have this problem any more. I'll resolve it as a duplicate of Bug 108940. *** This bug has been marked as a duplicate of 108940 ***
