I have tested this locally and it appears to me that all attachments should be broken for unprivileged users using the SelfService UI. This is a result of the changes made in 4.4.0 to attachments.
I have created a patch for this that appears to fix this problem. You will find that patch attached. This will be fixed in 4.4.1.
Description: Binary data
All other unprivileged users can attach files. Further experimentation has revealed that if the user sends an attachment by email it works (doesn’t via the web interface). Also, if I promote the user to the privileged level then she can add attachments via the web interface. I tried giving the unprivileged group all possible permissions but it had no effect.
Ah, I didn’t realize this user was unprivileged. And this is the only unprivileged users experiencing this trouble? Other unprivileged users and privileged users all are able to attach files normally?
I will take a look at this again with the Self-Service interface in mind.
