bug#2451: 23.0.90; rmail - semi-colon in rmail-primary-inbox-list and movemail

[Alfred M. Szmidt]

Been trying to debug this, and the only thing I have managed to figure
out is that replacing the semi-colon with something else makes things
work.  The following,

(call-process "/usr/bin/movemail" nil (current-buffer) nil
                    "pop://ams;address@hidden" 
"/home/ams/.newmail-ams;address@hidden" "PASSWORD")

always produces 

movemail: Could not create mailbox `/home/ams/.newmail-ams;address@hidden': 
Requested item not found

But if one replaces the semi-colon in the second argument
(/home/ams/.newmail-...) to movemail, things work.

Passing the same command line directly to bash works as well.

(How does one mark a bug as serious?)
