gdb didn't recognize -nofork, unfortunately, so I tried it without that. Here's
the stacktrace I got back:
Reading symbols from kate...Reading symbols from
/usr/lib/debug/.build-id/8d/9c38356e468a260900e0c4cb4b7e87722ad117.debug...done.
done.
(gdb) run

Since this doesn't seem terribly useful, at least to me, I went ahead and tried
to squeeze one out of KDE's crash dialog (happend to notice it while creating
the first one), and here's the results from that one. (I apologize, it's very
long)
