@simon mcvittie

Is this a dbus-python issue?

Something is going wrong at the interface between Python and C, and I'm not sure how it would be dbus-python's fault.

dbus-python has defined a type named MethodCallMessage, and is doing this:

def _message_cb(self, connection, message):
    if not isinstance(message, MethodCallMessage):
        return

and the SystemError we're getting is effectively an assertion failure from Python, saying that something is using Python's C APIs wrong: functions are meant to do exactly one of returning a value or raising an exception, but in this case isinstance() has done both. isinstance is a built-in part of the Python interpreter.

The SystemError has the exception raised by isinstance() attached to it as a chained exception; it would be useful if abrt could log that.

I don't know how this can happen; it's possible that this is a result of a bug in the C parts of dbus-python, or in any other C code used by setroubleshoot. People who work on the Python interpreter itself would perhaps know more.

If this was reproducible, then a developer who can reproduce it could attach a debugger to the Python interpreter and break on the line in _Py_CheckFunctionResult() where this SystemError is thrown; details of the backtrace and error state at that point might be enlightening.
