Very odd: It seems it's trying to insert the directory list into
the *Buffer List* buffer.

Could you trace the `dired-find-buffer-nocreate' function when it
happens, reproduce the problem, and post the output?  I.e.

M-x trace-function-backgroud RET
dired-find-buffer-nocreate RET
RET

and then post the contents of *trace-output*?
