Module crashes app

[beaur]

Module will occasionally crash the app when closing the scanner.

Looks to possibly be related to
#2
#4

Possibly some sort of race condition to do with the autofocus of the camera being interrupted or fired again after the scanner has closed.

And may be resolved by updating the the latest version of https://github.com/acktie/Acktie-Zbar-Android but I'm not sure how to compile that myself.

I've also had this issue and had to remove the QR code functionality entirely in the app because it was not acceptable. Were you able to solve this problem or find a work around?

I just fixed the cause in my app. The app opens another window after the QR reader, and in that window I had forgotten to unbind the alloy data bindings after my window was closed. Fixed by adding $.destroy() on that window closing event.
