Joining in to those that have the problem (reproduceble the same way), here
is what I also showed to Allan (in case someone is interested).


VERSION: 9092
This has only been a bug in later releases, as far as i recall, it wasn't a
problem for about 4 bug-fix releases ago (the hold option while pressing
update).

PROBLEM:
Textmate crashes when using the “select first word and drag it around” on an
empty selection (just the cursor).

STEPS TO REPRODUCE:
· Have the cursor located at a point. 
· Move the mouse at the EXACT same position as the cursor. 
· Click, hold and drag around. 

There is nothing in the selection, so it looks like you're dragging around
the cursor. When you "let go" of the selection (ie drop it), TextMate
crashes.
