Hi - I'm having problems with the following code where a QRunnable emits a
signal then ends. If you click the button it should print 1,2,3. It
sometimes works for the first few times but the wrong number of arguments is
given to the slot after that.
Is this a PyQt bug? I'm using 4.8.3 on Ubuntu (x86). I've tried setting
autodelete on the runnable to be false but that causes a crash.
