Yeah you are right!! Few hours ago I also started a thread for this.
Though ppl here suggested to clear data... Clear cache...use SUS etc etc...but the simplest and best way is to report a crash to developer. I am noticing that apps are crashing due to their compatibility with 4.3 system and the problem is solveD after a new update of app. I dont think that its the problem at our end.
I faced problems with MX player, opera mini, Google search, Skype till now.
MX player and Opera mini are now working fine after recent update...other two still crashing.
Cheers 🙂
