Do you have film in the camera? The LX reads reflectance from the film plane and if theres no film in the camera it will expose from the black pressure plate. Hence, longer shutterspeeds...

Now as I have my LX's put aside (due to digital...), I am just testing them time to time. Therefore, in the film chamber, I put a pice of paper cut out of an envelope that came from the bank containing some important documents. The Inner side of these envelopes are printed with white numbers on a dark grey background to make the contents unreadable when held against the light, this side is turned toward the cell. This printing is fairly near to the reflectivity of the film's surface. So, no need to put film in the LX when testing.
Testing regularly is important to keep the mechanics of the camera in good shape, rest rusts...

I didnt when I did the test so that may explain things too somewhat
