Problem reading .pdf file attachments in Thunderbird [10.04 & 12.04]
Normally with reading attachments to incoming emails one can just double left click the file name and all is well but with .pdf files this doesn't seem to work.
I am getting the message:
"/tmp/xxxx.pdf could not be opened, because the associated helper application does not exist. Change the association in your preferences."
All attachments seem to be moved to /tmp before reading. With other file types, .docx for example, there is no problem.
The system is of course set up to read .pdf files. The problem can be got round by right clicking the attachment and then selecting "save as" and then going to the saved file and reading it but this is annoying and not quite the point.
The error occurs in 10.04 & 12.04 but was working in earlier versions.
