Comment 3 for bug 588155

I have tried the dbgsym version of gnome-settings-daemon, however I don't see how to go about getting a backtrace on a program that automatically starts at login.

It doesn't seem to flag the apport automatic bug reporting thing, I'm guessing it starts after gnome-settings-daemon (or needs it).

I tried killing and restarting gnome-settings-daemon after login about 20 times without any problems. It seems to only happen at boot (about 1 in 5 times?). So starting gnome-settings-daemon with gdb in the console won't cause the problem since it works fine after login.

In addition to that those instructions on the wiki don't actually work, installing the dbgsym package doesn't seem to actually replace the binary according to the md5sum of the binary and gdb reports no symbols. No error is shown during the install, I tried with a normal apt-get, one that specified the version as shown in the wiki and through synaptic. I can't uninstall the non-debug version without it trying to remove most of Gnome.
