That bug is certainly relevant, but I don't get any error from  
khelpcenter, probably because it IS able to launch firefox.  Trying to  
open index.docbook doesn't open anything, but otherwise behaves the  
same.  Some use of help:// opened a page at help.com.  Most have  
khelpcenter show me the page not found message.  khelpcenter  
file://index.html gives me a popup "Unable to dcreate io-slave.  
klauncher siad: Unknown protocol 'smb', which makes no sense at all,  
since I have absolutely no use of smb on my PC.  It really does appear  
that some change in kio behavior is involved here.

I do not ever remember opening docbook files directly in khelpcenter,  
but I definitely remember opening the index.html produced by  
meinproc5.  However, also reading that bug again, more carefully,  
renaming index.html to index.cache does allow "khelpcenter index.cache"  
to open it with no problem.  I agree with David that there is a bug  
somewhere, but I don't really know what to blame.

What I might ask now is what is the recommended method of viewing the  
results of meinproc5 when editing docbook files.  Khelpcenter does not  
open the docbook files for me (I have not tried renaming) and having to  
rename index.html to index.cache every time (or using a symlink)  
doesn't seem like it should be necessary.  Is anyone other than David  
and mysef affected by this?
