Public bug reported:
In the beginning of /usr/bin/startkde there is a check to assure that qdbus can
be called.
A variable is set like this:
qdbus=QT_SELECT=qt4 qdbus
and later there is the real check:
if $qdbus >/dev/null 2>/dev/null; then
: # ok
else
unfortunately this is completely wrong, the variable assignment would call
qdbus directly with a wrong "qdbus=QT_SELECT=qt4" environment variable,
because the first unquoted space after a variable assignment separated the
environment from the command line to start
as explained in the BASH bible:
http://www.tldp.org/LDP/abs/html/varsubn.html#EX9, example:
GIT_DIR=/usr/src/repo/.git git status
Indeed, if I make qdbus non executable (or if I remove it) like `chmod
000 /usr/bin/qdbus` startkde would not complain as it should do.
This because the check `if $qdbus >/dev/null 2>/dev/null; then` is
always true as "$qdbus" evaluates to "qdbus=QT_SELECT=qt4" without
"qdbus" and an assignment is always succesfull in shell.
