I am running 0.8.5 beta on my mac under 10.8.3 and it runs fine until I try to use a bitcoin.conf file.
If there is a file, even if it is completely empty it will crash before the application even starts. All I receive is a message "Bitcoin-Qt quit unexpectedly." The is no log even generated.
I have tried redownloading the application and trashing all the files including the blockchain.
If I remove the bitcoin.conf file the application launches and runs fine.
Any help is greatly appreciated.
