No. Completely unrelated. You're seeing warnings about the 0.1% of the exotic 
mimetypes that can't be resolved, this doesn't affect normal operations.

That's a warning related to the kioslave implementation, I bet you see the 
same on Linux?

When launching khelpcenter without args, then clicking on Konqueror Settings 
Modules -> Bookmarks, I get this:

 khelpcenter(2220): could not start process ("--stylesheet", "/usr/share/kde4/
apps/khelpcenter/table-of-contents.xslt", "--output", "/var/tmp/kdecache-
dfaure/help/en__kcontrol__bookmarks__index.docbook", "/usr/share/doc/kde/HTML/
en//kcontrol/bookmarks/index.docbook") 

No executable name. That looks like a KProcess -> QProcess porting bug...
