libdbus : 404: assertion failed "(connection)->have_connection_lock" file "external/dbus/dbus/dbus-connection.c"

Hi Dbus members,

I am sorry if this is a wrong forum to ask any queries. But, I am seeing
the following error message in the android logcat after which system_server
crashes.
---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

I have seen people posting about this over the internet. But, I didn't get
any idea about whats going wrong. There was also a discussion about the *fault
addr deadbaad* which means heap got corrupted which could be elsewhere in
the code.

Is this a known issue. Has this already been fixed. If yes, can I get the
patch which fixes this issue.

"Looks like Dbus acquired a lock in a connection and then got interrupted,
reentered, locked again and unlocked, then resumed. At that point, the lock
was cleared, hence the assertion."
OR
"Someone freed the memory which it doesn't own causing heap corruption"

I appreciate if someone can help me on this.

Thanks much in advance.
