Emulator process exited with code 1

Hi,

I've been encountering this all day while trying to run an app in the Android Emulator,

print "[DEBUG] Signal %s received. Terminating the logcat process." % signum
                                                                      ^
SyntaxError: invalid syntax
[ERROR] :  Emulator process exited with code 1
[ERROR] :  Build process exited with code 1
[ERROR] Application Installer abnormal process termination. Process exit value was 1
