Package: xpdf
Version: 3.04+git20211021-1
Severity: normal

Dear Maintainer,

xpdf crashes the window manager when trying to scroll the table of contents
in the left-hand pane. The crash happens both when dragging the slider
and when using the scroll wheel of the mouse.

The crash happens with both of my window managers: blackbox and xfce.

The crash seems to be related to the content of the PDF file, or
maybe the size. The RP2040 reference manual is the file where I
discovered the problem, but there may be others:

https://datasheets.raspberrypi.com/rp2040/rp2040-datasheet.pdf

I've tried to reproduce the problem on my company laptop running
debian unstable, also with both xfce and blackbox, but the crash
doesn't happen there.

All the best,
Dave
