KWrite produces annoying console output (see Bug 173760) so I wrap it in a shell script as follows:

#!/bin/bash
/usr/bin/kwrite "$@" >&/dev/null &

This shell script works fine when I launch it from a terminal. However, if I use Plasma to run it with Alt+F2, the kwrite launches but I also get the following error dialog:

Sorry - Run Command Interface
KDEInit could not launch '/home/miller/bin/kwrite'

Possibly this is related to Bug 343673, which was supposedly fixed in KDE 5 and backported to KDE 4.  Note, however, that my problem is slightly different: I get the error only when I use Alt+F2 to run a shell script which invokes kwrite.  (And even then, the problem occurs only when I let KDE find the script on my PATH; if I instead type ~/bin/kwrite, the error doesn't occur.)

I am using KDE 4.14.3.

Reproducible: Always

Steps to Reproduce:
1. Create a shell script ~/bin/kwrite which launches kwrite.  Make sure ~/bin is on the PATH.
2. Press Alt+F2, type "kwrite", and press enter.


Actual Results:  
3. Error dialog appears which says, "KDEInit could not launch '/home/miller/bin/kwrite'"
4. KWrite is launched.

Expected Results:  
Step 3 above should not happen.
