[Octave-bug-tracker] [bug #63548] GUI closing suddenly when selecting a recently deleted file

[John W. Eaton]

Follow-up Comment #12, bug #63548 (project octave):

The following change in file_editor_tab::load_file avoids the problem for me. 
I'm not sure why load_file wants to open the file for reading only, but that
fails if the file doesn't exist.  That failure is apparently not fatal unless
we are trying to reuse an existing "unnamed" buffer.

+    if (!file.open(QIODevice::ReadWrite))

     int col = 0, line = 0;


The attached (larger) diff also avoids the problem by not attempting to reuse
an existing "unnamed" buffer.
