Its possible that stray light is getting to the camera`s meter when you look at the top lcd panel, to check cover the viewfinders eye piece and see if the exposure changes. It get this alot when shooting with my 20D when using a cable release and tripod. Canon actually have a rubber cover attached to the neck strap to prevent this. I simply put my cap ove the rear of the camera once composition etc is set. I usually only need to cover up when the sun is shining from the camera rear

One way to determine what shutter speed was actually used is to check the EXIF data after you've taken the picture. You should be able to access it somewhere in camera, but I'm not familiar with Sigmas, try checking the manual.
Nikon D300, D200
Nikkor 50mm f/1.8D, 55mm f/1.4 micro, 18-70mm f/3.5-4.5G DX, 80-200 f/2.8D
Apple PowerBook G4, MacBook Pro
Adobe Lightroom, Photoshop CS3

Absolutely! Stray light entering the viewfinder when your eye is removed is the most likely suspect I'd think too. I wouldn't be concerned there's a problem with the camera, just cover the eyepiece and you should be fine.

Yep my old Minolta Film SLR's came with an eyepiece cover attached to the strap for this very reason.

No it should not be possible! The mirror is blocking the light entering through your viewfinder.
