I am using debian sarge and tried to use konqueror (3.3.2) to reach a local 
ftp-server, that allows just one connection at a time. While this is 
no problem with all other tested ftp-clients, konqueror does not 
work properly. At the first startup only an empty window is displayed, 
although the ftp-server reports a successful login in the syslog. 

In my opinion this is because konqueror directly starts two connections and 
the second one gets no response. If I restart the ftp-server and konqueror, 
the directory is listed (I sippose from the cached results of the first attempt) and I can transfer files. However, changing directories again results in an empty directory list. 

Is there any way to tell konqueror, not to open multiple connections? 
While searching google I found different questions concerning this, but no answers. 
On my system I found a configuration file at /usr/share/services/ftp.protocol wich has the option 

maxInstances=2 

However, changing this to 1 did not help. 

I think, this is a design-bug in konqueror/kio_ftp.
