Bug 267438

Application: okular (0.12)
KDE Platform Version: 4.6.00 (4.6.0)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-25-generic x86_64
Distribution: Ubuntu 10.10

-- Information about the crash:
I get my bank statements as password protected PDF files ahich have attached to them a HTML page with the statement (the PDF is worthless, it's just some generic message stating that attached to this file is a statement, blah blah)

To extract the actual HTML I do the following:
- Enter my password
- Click Reviews in left hand pane
- I then open a tree right next to it showing Page 1, a clock and then the file
- To view the file I need to do "Save as"
- The file is saved, I open it and check the contents.
- The crash occurs when I close Okular (clicking on the X)

BTW I hope to remember putting on wishlist the possibility to view these attachments as with Adobe's product, showing directly under the text of the page, allowing for double-click to open it. At the moment it took me some time to figure out Okular could handle these files as well.

The crash can be reproduced every time.
