A good start is always a self contained script illustrating the problem.
I don't have GTKAgg installed here to try. Does the script below
reproduce your problem? If so, maybe someone else can reproduce it and
will take an interest in finding a fix..

## what I expect to be map center
X,Y=m(lon_0,lat_0)
m.plot([X],[Y],'ko')
plt.text(X,Y,'expected centre')
## actual map center
X,Y=m(int(lon_0),int(lat_0))
m.plot([X],[Y],'ro')
plt.text(X,Y,'centre with GTKAgg')
plt.suptitle(title)
plt.show()
