Depending on what the desktop-entry specification says this could be the 
intended behavior, i.e. prefer the application on the same prefix as 
the .desktop file over one in PATH.

For example in a scenario where you'd have myapp and myapp_entry.desktop both 
in /usr/ and /usr/local, the respective menu entry would launch the 
respective program.

However my guess is that it is actually a bug, so I suggest you file a bug 
report against kdelibs. Might be just in time for KDE 3.5.10
Would be interesting to know if anyone with a KDE4 setup can reproduce it.
