0.4.5 and 0.4.6 are affected by this bug. Users should upgrade to 0.4.7 and restore any missing transactions by running:
rescan 274524
When 0.4.8 is released, it will restore these transactions automatically.
Users who did not keep their wallet synced before upgrading to 0.4.5+ may need to do a full rescan (warning: this could take a long time) to restore previous missing transactions:
rescan
