"Binary package hint: evince

How to reproduce:

Open a small PDF with Evince. Activate the side pane (F9), set it to show the index. Close Evince.

Now open a large PDF, e.g. the PostgreSQL documentation (~14MB, ~1700 pages).

What happens is: It shows the side pane immediately on startup, showing "Loading..." for ~60s with 100% CPU load.

After "Loading..." was replaced by the real index, close the side pane (F9), then close Evince.

Reopen the PDF. Now it doesn't take up much CPU and only a second after the window was opened, you can press F9 to view the side pane / index. The ~60s of 100% CPU load are not required, they only occur if the side pane is initially visible.

> Thank you for your bug. Don't use the preview sidebar if you don't want it, that's an user choice. Making the preview requires CPU, it's a low priority task though and doesn't block the PDF rendering so that's not a problem
...
Please reconsider your decision to Reject this, as I think it was based
on a misunderstanding of what I wrote.

I wasn't talking about the preview, I was talking about the index. And
depending on how you use the program, the same feature/result uses
either ~60s of CPU time or less than 1s. This IMHO clearly shows that
the CPU time in the inefficient code path is wasted on something which
has no use and is not required to show the index.

If you need more information (or want me to try to explain it in a
different way, in case you think this might help), let me know.

Thanks,

Daniel"
