            Bug ID: 3322
           Summary: claws-mail crashes when clicking on malformed PNG
    Classification: Unclassified
           Product: Claws Mail
           Version: other
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P3
         Component: UI/Message View
          Assignee: users at lists.claws-mail.org

When I open a mail with a malformed PNG attached it will crash claws-mail. This
is what the console output says:
(claws-mail:11865): Claws-Mail-WARNING **: Failed to load image
'/home/hanno/.claws-mail/mimetmp/00000007.2670-sample.png': Fatal error in PNG
image file: Read Error

(claws-mail:11865): Claws-Mail-WARNING **: Can't load the image.
assertion failed: (animation)

Looks to me as first claws detects that the PNG has errors, however it will
still try to open it via gdk-pixbuf and there the crash happens.

Steps to reproduce:
* Take attached PNG image, send a mail to yourself with file attached
* Open mail, click on PNG attachment
