Version: (using KDE 4.0.2) Installed from: Ubuntu Packages OS: Linux I have noticed this primarily when running "kate" but I'm sure other programs can cause this problem too. When I open the KLauncher (Alt+F2) then type in "kate" and press enter really fast, it opens up KAtomic instead. This is caused by "kat" assuming KAtomic, and then when I type in the "e" it starts figuring out what app I am trying to open, but I press enter before it finishes doing so. The "e" is definitely there when I press enter, I can see it every time. If I wait half a second then it correctly opens kate. This is repeatable every time without fail. A simple fix to this would be no matter what the autocomplete says, when the user hits enter check if what he/she puts in is a valid command, if not THEN open the autocomplete value. To reproduce the error: Press Alt+F2 Type in "kat" Type in "e" and then immediately press enter. The wrong program opens.
klauncher is a totally different thing. What you want is called krunner.
I have something very similiar. Whenever I type bugs.kde.org<enter> very quickly I end up with bugs.kde.or not being a valid host name - suprise, suprise.
I believe this bug has been fixed with the new krunner in KDE 4.1. I used to be able to reproduce this all the time trying to run konsole and getting kontact instead, now it works just fine.
