The Trunk: SMBase-ar.111.mcz

Andreas Raab uploaded a new version of SMBase to project The Trunk:
http://source.squeak.org/trunk/SMBase-ar.111.mcz

==================== Summary ====================

Name: SMBase-ar.111
Author: ar
Time: 13 April 2010, 8:48:22.789 pm
UUID: 8e8debd9-dcc9-4149-aee4-36acf7595015
Ancestors: SMBase-ar.110

Add a workaround for the 'SMDependencyTest problem'. The issue appears to be caused by 'SMSqueakMap new synchWithDisk' creating an invalid checkpoint file (no objects in it) which when loaded later causes constant failure.

This may not be the intended behavior as it will cause the user being asked whether to upgrade the map from the net when opening the Tools tab in the object tools. However, it beats having a broken SqueakMap lingering around.
