Installed from:    Compiled sources

Several pages of the Cederqvist manual crash khtml (not just konqueror, also quanta shows this when previewing those files),  e.g. http://www.cvshome.org/docs/manual/cvs-1.11.13/cvs_4.html (so does cvs_16.html). khtml just writes loads of (~700kB) debug output (looking like a representation of a DOM tree) and then dies. 

This is the backtrace:

If needed I will also make the debug output or a valgrind log (which doesn't appear to say much) available.
