Hi there,

Skype crashed several times today during a videochat, and the crashlog it gave looked familiar: I've had other applications crash in the past few weeks with that same main title (probably very inspecific) of "EXC_BAD_ACCESS (SIGBUS)".

Can somebody take a look at this crash log and tell me if there are any leads to pursue for resolving any problems? I am using a recent MacBook Pro, and after buying it used a month ago I clean-installed a new system and firewire-transferred my files over. I guess some preference files or something from the old machine could be continuing a conflict on the new one? I used to get about rare kernel panics and frequent application crashes on the old one which would bring down Firefox, which I know is more often than it ought to be.

I appreciate your help very much and will quickly respond to any questions.

You shouldn't be getting anywhere near that many kernel panics.

Just to be sure: are you talking kernel panics

or just application crashes?

brickcam · Mar 23, 2008, 03:32 PM

Thanks for your reply. I meant application crashes: I've edited my first message above. I have had one kernel panic in the last month or so.

Cold Warrior · Mar 23, 2008, 04:08 PM

I'd definitely start by deleting Skype's plist, cache, and application support folder.

Also make sure you're using the latest version, 2.7.0.257.

brickcam · Mar 23, 2008, 10:38 PM

I have the most recent version. I trashed all of those files. Is this a good general method to use for any application crashes? Thank you.
