pysim-shell: export is missing some files - OpenBSC

10 Nov 2021

Hi,

i recently noticed that the `export` command from pysim-shell is failing on some basic
files like EF.ICCID.
However if i manually select the file it can be read. This happens on a generic USIM and
on the orange sysmousim-SJS1.
see the logs below to illustrate.

Cheers
