I came across this freakish bug yesterday in DestroyTwitter. As mentioned in a previous post, the next release takes great advantage of ContextMenus. In doing so, I managed to crash ADL without any report to the console or debug views. The problem lies in the data property of the NativeMenuItem class. Setting it to a particular Number will shutdown the app, as if you forgot to press 4 8 15 16 23 42 (LOST reference).

It gets weirder. When I set the property to the Twitter ID of my @destroytwitter account, it busts, which is how I found the issue. BUT! If I set the property to the Twitter ID of either my @destroytoday or @jonniehallman accounts, it works as expected. On top of that, if you convert the Number to a String, it works. If you place the Number within an Object like {id: $id}, it works. Below is the source code, give it a shot. I’m running Flash Builder 4 on Mac OS X 10.6.1. The bug has been submitted to Adobe—I’m dying to find out what causes it.

[note] @jonniehallman is my private test account, not my private personal account. It consists of thousands of tweets like “test”, “test test test”, “yet another test”, and so on.
