Wow, that was fast!

Yes, the debug patch changed that too. It's actually not a critical
situation to turn the fs to readonly.

Ok, I see now what's going on. I will work on a fix for that plus a
few other things I noticed are not right.
I'll likely submit the changes to the list by monday or tuesday, and
let you know in case you want/can test them.

Thanks a lot for the testing and reporting.
