I tried Ctrl+click (any button) on an xterm window, to bring up the menu (which I never used before; after reading a recent thread about X (in)security, I was trying to access the secure mode for password entering).
This crashes xterm. The logs: Warning: Cannot convert string "-adobe-helvetica-bold-r-normal--*-120-*-*-*-*-iso8859-*" to type FontStruct Warning: Unable to load any usable ISO8859 font Error: Aborting: no font found Google shows that this "adobe-etc" problem is recurrent, but no clear solution.
