Alternative crash for app adsdroid

[auermich93]

The original crash (https://github.com/tingsu/DroidDefects/tree/master/reproducible-cases/adsdroid-hu.vsza.adsdroid-1.7.2) is difficult to reproduce by a human since the search is often too fast to be interrupted by a rotation. A simpler crash can be reproduced by performing an arbitrary search, e.g., insert 'test' and then click on an arbitrary list entry. This will let the app crash with the following stack trace:

@auermich93 Thank you a lot for reporting the issues in detail! You could take a look at Themis, a more recent and well-maintained bug repository for Android apps. This repository contains 72 reproducible, real-world bugs. We also published a paper on this dataset (Benchmarking Automated GUI Testing for Android against Real-World Bugs).
