I have found 3 bugs when playing the latest snapshot. I am not sure if you were already aware of them or not, and even if you are currently fixing them or not, but I thought I'd point them out in case I can help out.

The first bug I found out, is when I went to sleep, it turned to day time like it should, but I still had the sleeping animation (with the button at the bottom saying "Exit Bed"), but whenever I tried to exit bed (I tried several things, pressing ESC, pressing the "Exit Bed" button, and even switching gamemodes.), it didn't work. I reloaded the game and was unable to re-create this glitch, so I don't have any available pictures for this glitch.

Another glitch/bug, since I have a skin with different layers, I usually am able to go into skin settings and turn off my hat, sleeves, etc., however when I tried turning off my sleeves, my character stayed the same (the sleeves were still there). I managed to fix it also by reloading my game, so I was also unable to recreate it afterwards.

Last glitch/bug, when I place a detector rail below a powered rail on a block diagonal to it (see image), when there is a minecart on the detector rail, the powered rail doesn't get powered, even though the detector rail has the animation of being powered. I was able to get an image of this since restarting the game didn't seem to fix the glitch.

Most of these glitches aren't game breaking, just rather annoying and are sometimes inconsistent. I hope that I was able to help out by labelling these bugs/glitches, and I hope you will be able to fix them!

Thanks!
