I'm currently testing the suggested fix in comment 27. It takes around 24 to 48
hours to see if it works without a problem. This might be a local database
corruption problem related to this issue. I just don't know yet. While we might
be running the same version of software, there might be difference at deeper
level in the system that is difficult to know about. Anything from version of
video card (I'm using 01:00.0 VGA compatible controller: NVIDIA Corporation
GK208 [GeForce GT 720] (rev a1)) down to some software library that I'm using
and has not been updated yet.
