gThumb makes uploading many photos to Facebook easier and faster. But not without hiccups though.
This morning I found "Application does not have permission for this action" error message. After a quick trial and error setting change, I found out that gThumb can not upload to Facebook album with public as privacy setting.
As soon as I changed it to other privacy setting, I can upload just fine.
It is not a fix actually, but a workaround of a bug.
I use gThumb 2.14.2 on Ubuntu 11.10
