Crash Reporter is an application available in Cydia for more than a year that tells us what problems our applications have and details the entire event that led to the blocking or closing of that application. When an application closes, crashes or causes problems in iOS, Crash Reporter makes a log detailing the problems caused by that application. In Crash Reporter you will find very nicely ordered all the logs available for your applications, arranged by name according to the permissions they have. The application also displays a list of possible other applications/tweaks that could have caused the problems so that we know exactly what is not working and how we can correct the problem.
Crash Reporter is available for free in Cydia and I for one recommend it because it could save you a lot of headaches.
