Hello,

I've checked out a fresh CVS repository today and i got a segfault while using the PDF viewer plugin:

Steps to reproduce (it segfaults everytime):

1) Open Claws-mail
2) Open mail with PDF attachment
3) Click on the PDF icon (right part of the screen)
4) In the PDF icon toolbar, click the "Document Info" icon
5) Claws-Mail segfaults

System is Linux 3.0 kernel on Debian SID, amd64.

Console ouput and GDB backtrace below.

Thanks,

Philippe
