I don't know when it happens, but it seems to just kick in after a while. Anyway, some keyboard shurtcuts stop to work, and when I go in and try to reassign them just to see what happens, a "cirlce" is inserted behind the shortcut, a picture will say more than I ever can explain. http://hem.bredband.net/perihelion/textmate.png
it seems my keyboard sends in this very weird thing, which only affects textmate. I have version 1.17beta (the latest beta released a while back, not the latest latest, and I do nothing cvs fancy or anything, I download from the main page every once in a while). I run tiger 10.4.2, on a powerbook, but I have an old "pc" ps/2 type keyboard hooked up through a ps2->usb converter. Since you'll probably ask me this, I'm gonna try with the built in powerbook keyboard now.
The powerbook keyboard seems not affected, and when I pull out and replace the usb cable it seems the problem disappears. Interesting to note is also that <div></div>[enter] does not produce <div> | </div> but instead <div> </div>
so in the end, I guess it's related to my converter somehow, but now you all know for the future :)
