In actions.c, commenting out
  1) the setenv entry in user_commands[] around line 76, 
  2) the setenv() definition around line 2086, 
  3) and the cmd_setenv() definition around line 2122
make everything work again.

on my system by apearing to break the launching of xterm.  =)


Here's the full backtrace from vanilla 1.1.1:
