hi,

is this bug consistently recreatable, looks like some corner case
Comment 4 Mohammed Shafi 2012-02-13 15:02:19 UTC 
unfortunately could not recreate it here, let me do some code review see if there is any bugs in locking
Comment 5 Adam Williamson 2012-04-19 01:00:57 UTC 
I don't see any reason for a commonbugs notification here, or any useful explanation of what the problem or symptoms are.
