Krusader crashes when closing certain popups with embedded terminal emulator open

[Ciro Santilli 六四事件 法轮功]

My krusader and its terminal emulator (Settings > Show terminal emulator) were working fine, when suddenly started crashing whenever all of the following conditions are satisfied:

- the termianal emulator was open
- I am using Unity. All works fine for: KDE Plasma, Gnome 3, and Cinnamon desktops

*and* at the moment when I would either:

- delete a file with right click > Delete > Delete (opens a popup)
- dclose the embedded editor ( opened with F3, opens a popup )
- close the krusader settings popup

The terminal emulator itself works fine though.

I imagined it was because of an update, so I backed up my config files and restarted without any config files (~/.kde/share/apps/krusader and ~./kde/share/config/krusaderrc),
and the problem is still there.

Also, I noticed that a new problem: Krusader crashes immediately after startup if I:

- remove the configuration files
- start Krusader for the first time, he asks me for the initial configurations I go with defaults
- select Settings > Configure Krusader > Startup > User interface > Show terminal emulator > Apply
- restart krusader

Now every time I start Krusader after that it crashes.

If I erase the krusaderrc line:

    Show Terminal Emulator=true

It can startup again as before.

The error message on the terminal from which I launched krusader is the same in all cases:

krusader(19916)/kdecore (KLibrary) findLibraryInternal: plugins should not have a 'lib' prefix: "libkonsolepart.so"
The program 'krusader' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadWindow (invalid Window parameter)'.
  (Details: serial 1884 error_code 3 request_code 20 minor_code 0)
  (Note to programmers: normally, X errors are reported asynchronously;
   that is, you will receive the error a while after causing it.
   To debug your program, run it with the --sync command line
   option to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)

Status changed to 'Confirmed' because the bug affects multiple users.

I have the same problem after recently qt packages updates, but it's doing this even with terminal emulator turned off.
The same problem is with Dolphin.
