user5757: About all one can tell from this log message is that the bitcoin-qt application crashed.  It doesn't contain details as to why.
One possible cause is that the blockchain files are corrupt, which could happen because of a previous crash or if the computer is turned off without closing the app properly.  You could fix this by reinstalling  the application (but make sure to save a copy of your wallet.dat file or you will lose all your coins).
It could also be a bug in the application.  If you can reproduce the crash, you can report it at https://bitcoin.org/en/bitcoin-core/contribute/issues
