Hello all, I have created a new debbugs to discuss and resolve the issue with the error message formatting and it not generating a backtrace: https://debbugs.gnu.org/cgi/bugreport.cgi?bug=28797 For the issue pertaining to this bug, the last relevant updates were: - https://debbugs.gnu.org/cgi/bugreport.cgi?bug=28792#11 - https://debbugs.gnu.org/cgi/bugreport.cgi?bug=28792#44 Let's continue from there... why does that error show up on trashing (i.e. moving, not deleting) a directory, dependent on the value of trash-directory and the location of the directory I am trying to trash? Sorry for taking discussion off-topic. > -- Kaushal Modi
