I have Thunderbird version 17.0.8 for ubuntu.
I install the latest xpi from file available for thunderbird: 4.1 29/8/2013.
I cannot make new task with email. The task is created but it doesn't link to an existing email. In the link there are some numbers and letters as [[thunderbird
and when I try to open it it send me to a new email.
Can you fix this issue?
