xaralx essential functions fail silently

Binary package hint: xaralx

installed XaraLX on a laptop, but basic functionality is not working. To re-create bug:

1) Create new document.
2) Draw a filled circle.
3) Create a new document.
4) Switch back to first document and attempt to select circle.
  Cannot select object, cannot close document, cannot print document ...

HOWEVER...

1) Create new document
2) Draw a filled circle
3) While circle is selected, Edit --> copy
4) Create a second document
5) Edit --> Paste -- it works!
  (However you cannot switch to another document and perform the action again.)

During all of this, the only error messages on the terminal are:

(xaralx:12094): Gdk-CRITICAL **: IA__gdk_window_get_origin: assertion `GDK_IS_WINDOW (window)' failed

(I also saw a WARNING message on the terminal but I haven't been able to immediately re-create it.)

You can open and save XaraLX documents (as long as you don't switch to another XaraLX document), but SVG export is completely useless. It creates a file containing only comments.

1) Open terminal
2) type $ xaralx
   XaraLX opens a new document
3) Draw a filled circle
4) File --> Export... choose SVG
5) Saved SVG file essentially empty except for comments.

When I did this, the resulting SVG file contains lots of comments like this:
<!-- entity tag ="nn" -->
where each nn is a number between zero and 4120.

INTERESTINGLY, if you add a filled RECTANGLE to your drawing of filled circles, the exported SVG file will contain just the rectangle. !!!

I believe Xara LX sometimes behaved differently when it had been launched from a terminal window instead of the normal GNOME menu launch, but I haven't been able to identify the exact differences.
