After upgrading from 4.0.7 to 4.1beta I encountered a problem listing directories on a specific system. The error I get is this:

Code:

Error listing directory '/home/user'.

Unexpected directory listing line 'total 171492'..
Invalid rights description '[0mtotal '


I'm wondering if this relates to escape codes in my shell's prompt or escape codes for a coloured directory listing. I would guess the former since the total appears on the first line and isn't coloured.

It could also relate to the preexec() and precmd() lines I have set in zsh to set the contents of the terminal program's title bar.

Anyhow, it's not a problem in 4.0.7.

Can you post a log file both for 4.0.7 and 4.1? Thanks.

I think I found the issue while examining the logs. It seems 4.1 doesn't unalias "ls" which I have aliased to 'ls --color' in my shell profile. 4.07 shows the unalias "ls" command in the log (I've put some context around the 'ls' line):

Code:

unalias "cd" ; echo "WinSCP: this is end-of-file:$status"
unalias: no such hash table element: cd
WinSCP: this is end-of-file:1
unalias "ls" ; echo "WinSCP: this is end-of-file:$status"
WinSCP: this is end-of-file:0
unalias "groups" ; echo "WinSCP: this is end-of-file:$status"
unalias: no such hash table element: groups


There is no 'unalias "ls"' line in the 4.1 log.

I'll post the difference between listings with and without colour as shown in the logs.

Getting current directory name.
pwd ; echo "WinSCP: this is end-of-file:$status"
