There's another thread of you running which is very similar:
Please, do not double post. It makes really difficult to keep track of how your problem is being taking care of(think if now someone answer the other thread, then we would have 2 equal threads with the same problem, by the same person. It's quite annoying). If you feel that you did not get an answer, you can simply write "bump" or whatever you want to make your thread goes up again. There's a time for doing so as well (I think it's each 24 hours). Please check the rules for more information:
About your problem, the best way of tracking a problem is by running the application through a console. Type konqueror on a terminal and see if it returns any error message.
There're a huge possibility that, during the installation, you've forgotten to add some essential packages. I did it a couple of times without knowing what a package was for just to keep the installation smaller. Just do not install packages that you know what it does, and that you know you wont need.
You profile is very vague as well. There's no description of which Linux distribution you are using, for example. If it's Redhat, during the install process, it checks for the dependencies and, if a dependency problem is found, it asks you to install the missing packages. You should say yes.
The best thing to learn Linux is to first have a full working Linux. Fixing broken packages right when you start using it is painful. If I'd you, I'd make a full installation to make sure all dependencies are matched, then keep using it and learning with a 100% working system. Just a tip.
