Anjuta crashes when open *.ui file

[Nguyen Manh Truong]

I'm using Anjuta IDE version 3.12.0, Ubuntu 14.10 64bit. Whenever I open a *.ui file, Anjuta crashes:

    if I double click at the *ui file, or right click and choose Open or Open with Glade interface designer, the IDE crashes.
    if I right click at the *.ui file and choose Open with Glade it open normally.

Same problem on Anjuta on 15.10.

Trying to open the UI file on a brand-new GTK C project causes:

This probably reflects a bug in the program.
The error was 'BadWindow (invalid Window parameter)'.

  (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 GDK_SYNCHRONIZE environment
   variable to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)
