Can't debug android app on actual device

I've been trying to debug my android app on a Sony Experia e4g phone (usb debugging is enabled on the device) but with no luck. The error message I get is the following:

10-20 18:19:49.760 9504-9511/com.jeronimo.superfan I/dalvikvm: Debugger is active

10-20 18:19:50.202 9504-9511/com.jeronimo.superfan A/libc: Fatal signal 11 (SIGSEGV) at 0x0000000a (code=1), thread 9511 (JDWP)

This happens immediately after the debugger attaches itself as you can see from the timestamp.

The app runs perfectly ok on the phone and on the emulator and I can debug it on the emulator.

I've searched on the internet a lot and found that this has to do with the devices memory but nothing I have tried works.

I'm developing on a Win 8.1 pro machine with Android Studio 1.4 and the latest SDK.

I've even created a new project with a blank activity (template from Android studio) and the same thing happens.

It's driving me mad because I can't finish my project. Any ideas are greatly appreciated.
