PIN activity crashed (force close) when a button pressed

Android version: 2.1 update 1
Phone model: Sony Ericsson Xperia X10

There was something weird happening with my phone. Then i restarted my phone, this app gone missing. After that, i restarted it once more. Financisto appeared, but when i started the app (I'm using PIN security) and pressed a button (any button), the app crashed. So, I connected my phone to a computer, and checked at the DDMS, here's the stack trace:
