That is the big chance we're taking by installing software from extras-devel. It is an unstable repository, only meant for testing very unstable applications. When you install something from there you should be prepared to crash your device completely. As a developer it is easy to be unlucky enough to create a little bug causing havoc. That's what the repo is for - finding those bugs so they can be avoided in the final application.

I think we should be patient with Rachol, the developer. He's not doing this as his full time job, and something else might take all his attention at the moment. It doesn't even have to be something serious - it could just be that he's run out of spare time for now.

I believe he deserves a lot of respect for what he has done so far and hope he soon returns to finish the great project he has started!

However, I hope he will release the source code for the application too. That would make it easier for more people to help him out fix the bug causing the crash
