Hi,
I have an issue with opening an ods-file (attached). The following
error is thrown when trying to open the file (either via GUI or
script):

Interestingly, the xlsx-equivalent
does not provoke an error and gets loaded properly.
I am using a recent gretl snapshot from last week on Ubuntu.
Just another minor thing: While drag-and-drop works for the xls(x)
file type, it fails for ods. Might be a bug or simply not
supported (which would be totally fine).
Best,
Artur
