Android 2.1: Grateful for crash analysis help: sig

Question

The output at this post's bottom is produced shortly after cancelling bluetooth discovery within my app.

Can you please help me identify what goes wrong?

I've attached an uncaught exception handler to my app which indicates no exceptions have been thrown, so this crash log is all I have to go on.

The most useful and human-readable lines seem to be:

11-10 11:36:55.854: I/DEBUG(19383): signal 11 (SIGSEGV), fault addr deadbaad
11-10 11:36:55.883: E/WindowManager(1197): find target window =null,but mFocusedApp!=null!

However I can't discern much from these.

Here's the output, I'd be very grateful for any suggestions.

Answer 1

This indicates a bug in the firmware.

If this is a modded ROM, contact the makers of the mod with this information.

If this is a standard ROM, if you can create a project that reproduces the error, post that and your error information to http://b.android.com, unless you see that there is already an outstanding issue for these symptoms.
