Package: less Version: 551-2 Severity: normal Hi,
I started less with piped input `cat file |less` and hit `s` to save the
data. Unfortunately, I've selected a directory like `/tmp` and hit `D` to
“Don't save.” Then I hit `s` again and selected the directory again and less
crashed.
I have the environment variables `LESS=-ij3MqRSWz-2` and
`LESSOPEN=|lesspipe %s` set.
This is the backtrace:
