We need to know which one, and how it got passed nil instead of a string. One thing you can do to prepare is to update to the most recent version of the net-utils package. Recent versions of the emacsbug library give very detailed information about your configuration and the state of XEmacs at the time you start the bug report. If you get such a warning once, type M-: (setq debug-on-error t) RET. Then try the operation again. This will very likely produce the same error, and then will print out a trace of the functions which are active at the time of the error. This narrows the field considerably.. Finally, if this doesn't seem to help, do M-x report-emacs-bug _immediately_. This will tell us what your most recent commands have been. -- University of Tsukuba Tennodai 1-1-1 Tsukuba 305-8573 JAPAN Institute of Policy and Planning Sciences Tel/fax: +81 (298) 53-5091 _________________ _________________ _________________ _________________ What are those straight lines for?
