I created the by the add-on requested folder with rights 700 (what else?), then chose that folder in the browsing mask. I gave the "new local folder" a name, chose subfolders and had the same problem as CarlB.
Following his instructions, I closed thunderbird, then removed the newly created folder (rm -r).
After restarting thunderbird the folder was recreated, but with rights 711. Btw, files in there are created with rights 600.
Seems to work fine now.
