The crash only happens if there isthis happens only when the application uncleanly exits. if you notice in the bug reports you linked to there was a problem elsewhere (e.g. an xioerror, an uncaught exception, etc.) and that caused an abort of the process with an unclean exit which then triggers this problem. the cause of the crash was never the WeatherEngine itself, but rather a crash in WeatherEngine was triggered while the application was otherwise closing down due to an error elsewhere that was itself bringing down the application. DataEngines created by DataEngineManager *must* be released prior to application exit. and normally this happens except in such cases where the application is brought down by an abnormal situation. so while you can make the changes David suggests, it will only change the backtraces in those bug reports but not actually solve anything in the real world. the aborts will still happen as a result of the underlying error. p.s. this probably belongs on plasma-devel rather than kde-core-devel ... -- Aaron J.
