Fish stopped working

Dear all,
I was using konqueror (and I like it a lot) to connect through fish to ssh remote folders.

For some reason the last days after writing in konqueror fish://username@host:/path (I am using history so there is no typo in reality in the link) the authentication pop up is displayed.

I give user name and password, which is done succesfully and then… nothing happens (normally the folders and files icons would appear)

My ssh connection to that host works perfect (I can connect through konsole). I guess that the problem is in konqueror but I am not sure what should I try next for fixing that.

I am running a

 uname -a
Linux myhost 3.1.10-1.16-desktop #1 SMP PREEMPT Wed Jun 27 05:21:40 UTC 2012 (d016078) x86_64 x86_64 x86_64 GNU/Linux

withe kde version 4.7.2 release 5.

What should I do next to discover where the problem resides?
