> How do I do that?

You should get a crash symbol in the system tray when it crashes, click on it
to open the crash report dialog (drkonqi) that would show the backtrace on the
"Developer Information" tab (and allows you to directly report the crash to the
KDE developers).

Or run it inside gdb ("gdb kinfocenter", then enter "run" to start it) and then
enter "bt" after it crashed.

> Do I need certain debug symbols?

Preferably yes, although even without it may be better than nothing.

drkonqi has a button to install the relevant debug symbols automatically, gdb
will print messages about what packages to install (like "Missing separate
debuginfos, use: zypper install kinfocenter5-debuginfo-5.12.5-230.1.x86_64")

In any case, you need to enable the debug repo (e.g. in YaST->Software
Repositories), the debuginfo packages (that contain the debug symbols) are not
part of the main Tumbleweed repo.
