Could you please provide an example of an invalid QR code that crashes the app?

A QR code that has a content like "ftp://ftp.heanet.ie" or "http://www.google.ie" will result a pop-up error message:
Error, Key not recognised

However, when a message like "this-is-not-a-valid-qr-code" is passed through QR code the application crashes.

I used QR generator from here:
http://zxing.appspot.com/generator/

Version used: 0.54
Android version: 2.2

I was not able to reproduce this. Here are the steps I took:

1. In the Authenticator app, Menu -> Scan a barcode
2. zxing barcode scanner opens and scan the barcode at
   http://chart.apis.google.com/chart?cht=qr&chs=350x350&chl=this-is-not-a-valid-qr-code
3. The dialog "Error, Cannot interpret QR code." is displayed.

I'm running 0.54 from the Market on a recent build of Android with Barcode Scanner zxing 3.53

The attached qrcode image crashes version 0.62 on android (marketplace current version) and it is impossible to restart, requiring a reinstall and deletion of existing data/keys.

This bug occurs every time for me even after uninstalling / reinstalling. My phone is android 2.2 - I'm assuming unless this bug doesn't replicate on other devices that it is an issue with the authenticator app.

Thank you for the report! This particular issue is caused by an invalid character '1' in the "secret" parameter in the URL encoded in the QR-code.

We're working on a fix. For now, the workaround is to clear application's data (thus losing key material of all accounts configured in the application) or to downgrade to v0.54 (attached) which will not crash and will thus let you delete the "offending" account.

Glad to be of help. Discovered the issue while experimenting with the system. Thanks for quick response.

I look forward to a future update and will avoid testing with invalid keys for now.

Thanks for providing such a useful application.
