I run KOReader with KSM on Kobo A1 LE. I am modifying the frontend/apps/filemanager/filemanager.lua file to add an extra button in the long-press-context-menu for files or folders in file manager.
If I add the button as the first one-line button, the whole thing crashes. If I add the button at the end, after the set-as-home-directory button, all is OK.
This does not happen in KOReader for Kindle. Here is the relevant crash.log. Any help is appreciated.
