NSOperationQueue on 10.5 and crashing flickery

I received three (yes, I counted them) crash logs of flickery with this particular problem, so it’s not really common, but I still thought I should let you know what it’s about.

Apparently, when using NSOperationQueue and NSOperation on 10.5 there’s a chance an exception is thrown and the application will crash.

I’ve been checking on this for quite some time now and finally stumbled upon this blog post by Rogue Amoeba’s Mike Ash.
What he’s saying is that NSOperationQueue is buggy on 10.5 which causes applications to crash. This is really sad because it’s such a great tool for us developers.

I haven’t been able to work around this issue yet, however, I’ll keep working on it and see if I can do something about it, short of rewriting the whole application.

Fingers crossed.
