NLA causing BlenderPublisher2.25 to quit

Only today, and only on one of my files, whenever I open the NLA window BlenderPublisher2.25 quits.
Mysterious. Any ideas?

I’m still having the same problem with this particular file and now it also causes Creator 2.23 to quit when I’m in the NLA for each bone and I hit ‘home’ to see all bones that have actions.
ALSO, in Publisher the increments NLA systems are shown in half frame increments, making it almost impossible to navigate and see keys - they fly by. Any help would be appreciated. I need to repeat some actions and the way it is now I can barely find the keys to copy and paste them.
