So I went from DP4 to DP5 yesterday and suddenly Safari stopped working for good, throwing this crash between 1 and 10 seconds upon launch : It's like it's trying to add the launch page from Safari into their history SQLite database, but they're injecting empty data. I do have a lunch page when I start Safari, it's not a blank page. Here's the crash log when I put in a blank page : I tried disabling extensions, deleting history, deleting preferences, etc. but nothing seems to fix the problem. I have an iMac 27-in from late 2013. Does anybody have a fix in mind ? Else I will just report it to Apple and cross my finger for a fix in DP6. I can't stand other browsers on the OS X platform.
