KRun Breakage

Hi,

When I try to open a remote text file in Konqueror (such as one of the 
changelogs from ftp://ftp.kernel.org/pub/linux/kernel/v2.5) Konqueror calls 
KRun::run() to open the file. KRun then decides to use kfmexec to open the 
file with Kate, via KApplication::startServiceByDesktopPath(). This seems to 
be the first bug, as kate.desktop specifies that Kate should be executed as 
"kate %U"; KRun should just start Kate directly with the remote URL as a 
command line argument.

Next, kfmexec downloads the remote file and runs Kate. However, it seems to 
think Kate has exited before it has even finished starting up. This causes 
kfmexec to remove the temporary file before Kate has a chance to read it. The 
result is Kate showing a blank file. This second bug seems like a bad 
KUniqueApplication interaction.

The attached patch hacks around the problem by not removing the temporary file 
in kfmexec. This is far from a solution, and I've only included it as a 
demonstration of what's going on. Any help at all would be greatly 
appreciated, as I'm not very familiar with this code.
