If I connect to an AIX server with FTP, I'm unable to change directories by ENTER or the cursor keys. I always get the following error: "Error: Could not enter folder: <foldername>". After some investigation, I realized this is because there is a space character between end of the current location and the name of the directory that I'd like to change to. For example: let's assume that the current location is /usr and I'd like to change to /usr/lib. The error message I get is: "Error: Could not enter folder: /usr/ lib" note the space character before "lib". I use Krusader 2.4.0-beta1 with KDE 4.8.2 on Ubuntu 12.04. Passive mode is enabled in KDE system settings. Reproducible: Always Steps to Reproduce: 1. Connect to an AIX FTP server 2. Try changing to any directory Actual Results: Error: Could not enter folder: <foldername> Expected Results: Change to the desired folder The server runs AIX 5.2 PPC (64bit)
Does this happen only with Krusader, not Konqueror/Dolphin/other ftp clients ?
Yes, it happens with Konqueror as well.
By the way, it doesn't happen if I use sftp protocol instead of ftp.
Hi, I have tested this on Ubuntu 12.04, with Krusader 2.4.0-beta1 and can confirm this behaviour. This bug happens also with AIX 5.3.0.0 and 6.1.0.0 as FTp server. As a sidenote, this bug also happens with MidnightCommander. Other FTP clients seem to work fine. Current status indicates that you need info. Please specify what exactly do you need, cause I really like Krusader and use it as everyday tool in my work. Lack of FTP connectiont paralyzes my work. What can I do to help you resolve this bug?
Recently nothing was happening around this bug, so I investigated it a bit and have noticed following relation. The files with additional space in name are ONLY the ones, which have NOT been modified at current day. In such cases the 'hh:mm' part of modification date is replaced by 'YYYY ' followed by additional space, which makes krusader to add one additional space to file name. I am attaching screen shot, illustrating this situation: Bug_300988_Cannot_change_directory_on_FTP_connection_with_AIX_server.png
Created attachment 72579 [details] screen shot identifying names with spaces at the beginning.
Apparently this happens because the fix for https://bugs.kde.org/show_bug.cgi?id=88575 (Do not trim whitespaces from filenames.)

Well, since I am responsible for that fix, I looked into this and came up with a potential fix. However, I do not have access to an ftp server on a AIX machine and as such no means to test the patch. Can any of you either test the patch (you have to compile kdelibs 4.9 branch from source) or provide a test ftp server on an AIX box ?

Git commit 014e8f3ca18b0dd22e041f9785afc578f1ebc51b by Dawit Alemayehu. Committed on 29/09/2012 at 08:24. Pushed by adawit into branch 'KDE/4.9'. Make sure bogus whitespaces do not break listing. This patch addresses the regression caused by the fix for bug# 88575. Namely not trimming the white spaces from filenames breaks AIX ftp servers which seem to add bogus whitespace between the date and entry name.

Hello Dawit, Is this patch already in some packaged version I could install? i am asking because Ubunu team seems to not care much about Krusader - there is still 2.4.0-beta1 in Ubuntu 13.04.

It is not the Krusader version that matters for this patch. It is the kdelibs version. If it is equal to or greater than 4.9.3, then this patch should already be included.

Any clue?
