However, given that I do not work in this area on a more or less regular basis I guess it could have been reasonably predictable that I would make that mistake. Anyway, here is the confirmation that it is emacs that is triggering the problem: Breakpoint 1, ProcGetInputFocus (client=0x1805900) at events.c:4870 4870 events.c: No such file or directory. (gdb) p *client->clientIds $1 = {pid = 15289, cmdname = 0x1805c80 "/usr/bin/emacs", cmdargs = 0x1805ca0 "--smid=2d8141d58-12db-49a6-8893-2addd79140b3 --no-splash --chdir=/work/rjschwei/devel/smt apache2/conf.d/smt_mod_perl.conf"}
