[Rails] Weird exception

[Martin Gamsjaeger]

Hiall,

I'm currently experiencing with javascript a lot, and I have some pretty
messy code trying to handle some realtime validation issues. Although
everything pretty much "works alright", i.e. does the right thing but all
the time shows "A script on these page seems to be slow ..." dialogue. So my
suspicion is that the trouble definitely starts in my code, however, I'm
getting this weird rails exception more or less regularly, after which only
deleting the session file under /tmp will allow me to log back into my app.
Any ideas? (I'm - as you can see from the stacktrace - running the whole
thing on windows, and no, this was not my decision :)
