Lars, please post your output.log file from the PB program files folder. Also, when are you getting the messages? Is it when you do a particular operation? It could simply be a bug in the code and not a true corruption.
I am experiencing the same errors on two of the files I use regularly.
As I've just completely started over with a clean install of OpenSuse 11.0, I'm sure there are a few extra zingers in my config that will be clouding the issue here.
In my output file, you will see that I inadvertently clicked the PB icon twice, and so two instances tried to load the same file.
You will also see that the files are read-only. I've confirmed that there is a file-access issue on my end....
Having now straightened out the file permissions issue the data corruption error has gone away.
When loading 18.104.22.168, The errors appear on PB startup just after the tips screen loads, while the last-opened pb file is loaded. The error seems to display three or four times as the file opens. I attempted to brainzip the loaded file, and did so successfully, but opening that brainzip failed with error.
Be vewy quiet. I'm hunting wabbit.
