Probably the best thing to do is get a bug report on bugzilla and attach

You need to create an account first before you can add a bug.
Please add you app to the AppDB as well. At some point these two
databases should be linked and It will be easier to match bugs to apps.

You need to create an account here as well before you can add an app.
If you need help with any of this I will do what I can.
