Comment 2 for bug 1841801

The program does not crash anymore, but there is still an error dialog popping up: To reproduce:
-create an empty child sheet,
-cut and paste it (without saving it before)
Now you get the error window (this time the path is correct but since the file does not exist on disk until you save the schematic you get the same error pop-up saying "Error occurred loading schematic file... ").

Moreover, if you put some components in the child sheet (without saving it),go back to parent sheet and cut and paste the child sheet block you loose the child sheet content (as above: it was not saved during the cut operation and was not on disk). May be saving the child sheet content on a temp file on cut operation could be a solution).

Cheers.
