    meldapp: Rearrange failure-on-launch logging for better feedback
    
    In the case that we actually hit a failure on launch, the raw exception
    text isn't really enough; we need the traceback. This will only be
    logged at debug level anyway, so no one will see it without manually
    changing the log level.
