Although it's still a mystery as to what the problem actually is.
It is a known silicon bug. Quote from the datasheet:
Reading EEPROM by using the ST or STS command to set the EERE bit in the EECR register triggers an unexpected EEPROM interrupt request. Problem Fix / Workaround Always use OUT or SBI to set EERE in EECR.
