Nope, I don't think so:

[snip]
dtk_AT_minibox:~$ aptitude search dash
i dash - POSIX-compliant shell
p dasher - A graphical predictive text input system
p dasher-data - Data files for dasher
dtk_AT_minibox:~$ dash
$ exit
dtk_AT_minibox:~$ which dash
/bin/dash
dtk_AT_minibox:~$ ll /bin/dash
-rwxr-xr-x 1 root root 82K 2010-04-01 21:22 /bin/dash*
[/snip]

>> /etc/X11/wmii/wmiirc: line 1: !/bin/dash: No such file or directory
yeah, that's rather a syntactical problem -.-

[snip]
dtk_AT_minibox:~$ head -n3 /etc/X11/wmii/wmiirc
!/bin/dash -f
# Configure wmii
wmiiscript=wmiirc # For wmii.sh
dtk_AT_minibox:~$
[/snip]

The first line obviously is a broken shebang and should rather be
[code]
#!/bin/dash -f
[/code]
(don't know whether it's broken in die .deb or if I messed it up)

Fixing it doesn't make much of a difference though:
