All I am doing is to click on the black canvas while nothing is loaded.
Todays SVN of Avogadro.

You don't mention what tool was active, what engines were active, I am assuming this is on a Linux OS. It looks to me like it was the draw tool and it was attempting to add an atom. It seems to crash in Qt Core or libc though and I don't get why. I am not observing similar behaviour. Is this Qt 4.3.3?

I am currently on a different PC so I cannot check some questions now. What I can tell you:
The machine runs OpenSUSE 10.3 with Qt 4.3.3.

After recompiling Avogadro with installed libc-profile I am now getting this backtrace. To reproduce on this machine: Simply click on the canvas when no molecule is loaded.
It doesn't matter if I select any engines or not, in this case no engine was active.
It only happens when I am in the Draw Tool.

I just managed to crash Avogadro while an molecule is loaded. This means it doesn't matter if Avo has a molecule loaded or not, the Manipulationtool has a bug so that adding an Atom crashes Avo.

Can you run through gdb?
I think this is really weird. The offending code seems to be something like:
void Engine::readSettings(QSettings &settings)
{
setEnabled(settings.value("enabled", false).toBool());
setName(settings.value("name", name()).toString());
setDescription(settings.value("description", description()).toString());
}
These all look really safe. About the only thing I can imagine is if your settings file is corrupted. Try deleting ~/.config/SourceForge/Avogadro

Carsten reported via e-mail that this bug is now fixed in SVN trunk (now at 1100 or so). I'm marking this closed. Similar problems should open a new bug report.
