No idea if this is the cause.
Either way, I cannot replicate this issue on my CB 191 to CB205 upgrade tests, so it is most likely not a potential CB bug.
If you can provide exact steps to replicate this on a clean CB191 install upgraded to CB205 I will certainly spend some time trying again to reproduce.
Otherwise something else you have installed is causing this.
