Sorry, I cannot work with that limited information. As a notable example, I would like to see where exactly during the use of the pristine system emscripten emits its initial notice that it has created a configuration file. Until reproducible I am most likely to ignore this bugreport, considering it "a case of fly-by UFOs bit-flipping the data storage of the system". - Jonas -- * Jonas Smedegaard - idealist & Internet-arkitekt * Tlf.: +45 40843136 Website: http://dr.jones.dk/ [x] quote me freely [ ] ask before reusing [ ] keep private
