Visit some FTP site:
"C-x d /anonymous@ftp.gnu.org:/ RET"
Then try running a shell:
"M-x shell RET"
I see a backtrace:
Debugger entered--Lisp error: (wrong-type-argument processp nil)

comint-exec-1("shell" #<buffer *shell*> "/bin/bash" ("--noediting" "-i"))

I think I may have seen and reported this before - it does look familiar.
