specto crashes when monitoring file changes

Binary package hint: specto

Steps to reproduce:
1. Create a new file watch.
2. Set the update period to something short (eg, 1 minute).
3. Wait the required time and the daemon will crash.

According to the crash report, the python function being used doesn't have the correct number of arguments.
I was monitoring a file in a NTFS file system, if it makes any difference.
I am using specto version 0.2.
