I am not sure when this started, but trying to connect to ssh servers using 
fish with Konqueror fails with this message:

The process for the fish://ftp.mywebsite.com protocol died unexpectedly.

Nothing appears in the logs.  The same error happens with different servers.  
What might it be?

PS. I've tried revdep-rebuild and nothing seems to want to be rebuilt.
