You do need to manually install them, but you don't have to guess your suspects. When things crash you should get a window with debugging info (DrKonqi?) and then you can see whether you get a useful backtrace. If you get paths with linenumbers then you have good one. If it only shows an object name (*.so usually) you can usually find the corresponding package with: dpkg -S $(which <object-Im-looking-for>) and then search for a corresponding -dbg or -dbgsym package and install that. Once you've done that, reload the stacktrace and then it should be able to further specify the backtrace. Repeat this as often as needed/useful.
