Recently KRDC was updated, and today I cannot connect to RDP sessions anymore.
Also, I lost all bookmarks and the settings of KRDC's toolbar.

The symptom is that if I enter the address of an RDP host, KRDC prompts me for
the user, then (apparently) attempts to connect and then it suddenly returns to
the "new connection" screen, without any error or message whatsoever.

I know the xfreerdp works because I can connect to the RDP remote host by using
xfreerdp from the command line.

Here is the line from zypper history, referring to KRDC's update:

  2016-06-06
10:48:12|install|krdc|16.04.1-1.1|x86_64||repo-oss|bdca2dfa37147c9ec4f8962731f4a3702edc40af|

I tried to start KRDC from the command line to see if it sent some message to
the console, but all I got was this, just before the error:

  KBookmarkMenu::slotBookmarksChanged groupAddress:  "/0"

Another strange thing: if I enter "krdc -v" at the command line, this is what I
get:

  cristiano@xmper8q3:~> krdc -v
  krdc ��
