Just don't specify any binary to the gdb command line. Let it find the
correct binary from /proc:
$ gdb -p <pid>
This is because sometimes kdeinit4 is the binary and the application
is loaded as a shared library and gdb gets very confused if you tell
it where the binary is.
Also, always make sure that the debug symbols package is exactly the
same version as the package providing the binary. In some debug
packages dependencies are not strict and you might get version
mismatch.
