I also get a lot of

Same thing with

except without the other logs.

The app just crashed and now I'm getting the following every so often.

What I did

1. Upload as3.swf
2. Wait for it to load
3. Click on Help --> About --> OK
4. Click on Help --> Check for updates --> Visit homepage
5. Close out of the new tab
6. Saw that the app had crashed with these messages
7. Be sad

Reproduced this on another computer. Will try with a newer CheerpJ nightly.
