      Description

      Similar to QTCREATORBUG-22041, but that's marked as fixed, so it refers to a different issue (busybox stat) with similar symptoms.

      When deploying, QtCreator prints lots of errors, "Unexpected stat output for remote file <file path>". It's worse than just an error: as a result of the failure, it redeploys files which haven't changed, presumably because it can't confirm that they haven't changed. For a project which deploys many files (e.g. qml files), this considerably increases deployment time.

      I tried removing the previously deployed files, just in case they had been left in a weird state, but the problem persists. Here the stat -t output for an affected file:

      $ stat -t /home/username/qml/FileName.qml
       /home/username/qml/FileName.qml 2033 8 81b4 1000 1000 802 156140 1 0 0 1556884716 1556884751 1556884751 0 4096

      This issue essentially prevents me from upgrading beyond Qt Creator 4.8. I am happy to try running any commands or debug builds you suggest to try to work out what is causing the issue.
