I'm running emacs 23.0.60.2 from last week here. Since that I noticed 
some strange behaviour when trying to open a file by C-x C-f. What I try 
to describe here happens mostly after start up. A second try or any 
subsequent tries work (not always though, but the error occurs mainly 
after start up).

Description:

case 1:

Start emacs.
C-x C-f ~/path/to/file
emacs opens a second window, 5 lines high only, on the bottom of frame. 
In that window I see an other file that was opened on start up (I use 
desktop).
A second attempt succeeds.


case 2 (this one is worth):

If I export an *.org file sometimes an arbitrary existing file is 
overwritten!
Same as above, first attempt in session, subsequent attempts succeed.



I suspect emacs though, since I deleted all lisp files on my machine 
before installing. I used emacs 22 before (the current Debian testing 
package).
I searched the mailinglist for something on this but to no avail.

I'd appreciate some guidance in figuring out the reasons for this. Maybe 
some known problem that I missed here?
