This time, I installed tonfotos on MX Linux 23, which is based on Debian 12.
It installed and scanned my 35.000 images well.
On day two, I started to batch write people tags to general tags of the files (to have them permanently stored and be used by other apps).
It seems that this action (after a couple of times) makes tonfotos freeze. I had this feeling before, on Ubuntu and Debian 12.
The terminal gives this message: MenuCommand context_to_tag
After that, it produces no more output. The UI of tonfotos freezes.
Does this give you any clue, Andrey?
