Yes, I could reproduce this problem; but it doesn't occur any
more with xdvik-22.40c (I would recommend to upgrade to this
version anyway, which also fixes some bugs with virtual font
sizes when switching .dvi files).

Well, that's a rather silly message, isn't it? With xdvik-22.40c,
I get:

$ xdvi sample2:e.dvi
Can't open `/home/ulrich/tex/sample2:e.dvi': No such file or directory

which is only slightly better ... using a relative or absolute
filename, as follows:

$ xdvi ./sample2:e.dvi

does work, though. I'll file this as a bug on
http://sourceforge.net/tracker/?group_id=23164&atid=377580

yes but then it should accept a hex-escaped version, which
it doesn't ;-) All this URL handling is rather half-baked
and needs a rewrite (we even have a bug report for this on
http://sourceforge.net/tracker/index.php?func=detail&aid=417116&group_id=23164&atid=377580
saying `http and url handling too complex' ;-)
