Hi Josef,
Are you able to reproduce this? If yes, please tell details steps. Thanks! |

Hi Robin,
no sorry, we are not: we have no glue where it came from and it seemingly does not occur anymore. If I remember correctly, we may have moved the config's storage locations in the file system, and/or decreased the amount of builds to keep in history some time before this log occurred. However, these are only very rough guesses and presumably not very much related. Sorry for not being more helpful, maybe let's ignore it for now and close this issue. If it re-occurs we'll contact you. Thanks, Reinhold |
