Comment # 9 on bug 905082 from S J

In such a case, it must be some incompatibility in interface between gdb 7.8
and kdevelop because issuing backtrace command from gdb toolview manually does
produce a valid frame stack output but entries are greyed (cannot be clicked
on).

Debugging same code with gdb 7.8 manually (outside kdevelop) works fine as far
as I was able to determine. This seems to be some really silly problem, slight
change in format of gdb which throws off the toolviews, I wish I had more time
to learn how kdevelop toolviews interface with gdb and fix it.
