[DiapDealer]

I can't make the crash happen on my Arch Linux system. I can point to the apos_exceptions.txt file whether it's in my Documents folder or in /home/[user]/.local/share/sigil-ebook/sigil/ with no trouble (Using the 2.7.0 AppImage). I can't think why it would matter if the file location was read from the preferences .json, or if it was loaded via the gui QFileDialog.getOpenFilename. I'm using non-native dialogs so switching to, and browsing, normally hidden folders in /home/<usr>/.local shouldn't be a problem (and doesn't appear to be on Arch).

Do you happen to have a user name with diacritics in it? Perhaps I'm not handling something correctly when trying to print the path in the textbox after choosing a new file. Something that doesn't happen when reading the last used path from the preferences file. I'll keep looking.
