I attempted to use the library to send an INVITE message with multipart content. I created the multipart container by calling pjsip_multipart_create with NULL for the ctype argument, indicating the default "multipart/mixed" should be used. Later when the print method is called, a crash occurs. It appears to be a problem with the way the linked list of content-type parameters is initialized.
The following patch has resolved my problem:
