Ajax error prevents registrations for events (when many events)

This issue only seems to occur when there are a large number of past events, such as more than 350 events in the last 3 months. ( as a result I have been unable to reproduce this in the public CiviCRM sandbox)

In my environment, I am able to reproduce this by doing the following:
1) In the CiviCRM back -office, I click "Create New ... Event Registration"

2) Under the select list for choosing an event, I click the link "past 3 months"

Using Firebug, I now get the error message:
NS_ERROR_IN_PROGRESS: Component returned failure code: 0x804b000f (NS_ERROR_IN_PROGRESS) [nsICacheEntry.dataSize]
chrome://firebug/content/net/netCacheReader.js
Line 294

FYI: as a result of this bug, there is no means for the user to register anyone for past events. Even though they can see past events listed in the select list and they can choose the desired past event, nothing happens if they click the "Save" button on this page.
