Page layout editor copy-paste error

[Dino Ghilardi]

To reproduce the behaviour:
-Open page layout editor
-File->New to have an empty sheet (not needed)
-Add a new element (tested with line, text and box) to the sheet
-Select it and copy (ctrl-c or right-click menu)
-you get a window with:
   pl_editor information
   Expecting "'number'" in input/source "Sexpr_string" line 1, offset 24

If you try to copy-paste the elements of the default sheet, some work and same give the same error (with different offset)

Attached a file with just a line that issues the error with copy-paste.

Looking at the file, it seems that the end x coordinate has 14 decimal digits instead of the six used for start x,y and end y. may be it is related to this.
