I was importing some pictures into iphoto last night when iphoto stopped to respond and just showed a "finishing import" or something similar message. The colorful wheel was spinning around for an hour, but nothing changed. Activity Monitor showed a "not responding", so finally I did a "Force Quit". Now, do I need to worry about the library? iphoto did start normally again, and the number of pictures (about 40k) and events it showed is within the expected range. But still... I feel a bit worried. Is there a way to do a kind of consistency check to make sure that everything's fine... or am I overly worried?
