Comment 1 Amar Tumballi 2010-04-20 08:18:05 UTC 
Looks like a Out Of Memory issue. Need to reproduce and this should be gone with 'NULL pointer' cleanup process.
Comment 2 Lakshmipathi G 2010-04-27 09:56:49 UTC 
checked again with 3.0.3rc1 , but unable to reproduce this bug.
Comment 3 Amar Tumballi 2010-07-28 07:49:34 UTC 
it is surely a case of memory allocate failure. will be handling it as part of NULL pointer check bug.
