Yes it looks like same problem. My bug report Review ID is 1700023. I can not
edit or add more information to my bug report.
Its strange to me that Bug: 6892485 has "Low" priority. According to internal
rules in our company deadlock has "Critical" priority because it can lead to
loss of data. (application must be killed)
I'm sorry that I don't have time to make sample to reproduce this problem.
Maybe later.
Thank you for your time
Martin
