Random error after Mountain Lion upgrade.

I am suddenly getting the following error in build 797 after after Mountain Lion upgrade. Everything works fine even after that.

Runtime error bad argument #-1 to '?' (Proxy expected, got number) stack traceback: [C]: ? [C]: ? ?: in function '?' ?: in function '?' ?: in function '\_listener' ?: in function <?:517> ?: in function <?:218> <envelope xmlns:s="http://schema&lt;br&gt;<br><br>Did anyone encounter similar issue?

I’m not certain on this but I’d think that due to changes builds out pre-ML may have issues on it. Do you still get this error with the newer daily builds? [import]uid: 52491 topic_id: 29472 reply_id: 118697[/import]

I thought so as well. But I am getting the same error with 870. It happens so randomly, I cannot predict when it will show up.

Another interesting thing: the code I have been using with 797 for so many months, now crashes with command+R in 870, but works fine if I use Relaunch from the menu. If I change the code and the simulator tries to auto relaunch, it crashes as well. I have opened a bug for this part already. [import]uid: 19297 topic_id: 29472 reply_id: 118699[/import]

Glad to hear you opened a bug for that - could you perhaps open one for this error as well? I’m not able to try and reproduce it as I don’t have an ML machine here currently but if you file it someone in the office could give it a go.

Just to clarify, this error is present in all projects (sample code, etc) and not just one in particular, yes? [import]uid: 52491 topic_id: 29472 reply_id: 118850[/import]
