Comment 2 Petr Nejedly 2010-09-20 17:52:48 UTC

Thanks for a great test case causing the OS notification queue overflow.
The fix will be two-part:
*) correctly forward the overflow event to the infrastructure (and prevent NPE)
*) Do a full refresh of all the registered folders.

Comment 3 Petr Nejedly 2010-09-20 18:02:41 UTC

The NPE part is fixed:

The overflow handling is filed as: 190470
