Same for me here. Can't say the exact cause of the problem, but using PageUp/Down or even Up/Down arrows to navigate through a document(single click is enough in either case) results in segfault. I'd suggest masking the ebuild if the problem occurs to many people since the application is simply unstable. Reporting to upstream would be wise too if it hasn't been reported already. Another thing to mention is that if you try scrolling through a document using your mouse roller it works fine, at least for me. It would be nice to see this application working smoothly since it is the simplest, dependency-wise, gtk-based PDF viewer out there. Last but not least, the necessary `emerge --info`:

[Comment 3 David Shakaryan (RETIRED) 2007-10-21 08:30:43 UTC]

I'm not able to reproduce this bug, it seems.

Anyhow, I checked their homepage and found this bug: http://trac.emma-soft.com/epdfview/ticket/70

From what I understand from the description, this only applies when the page is set to the width of the browser. If you have been using this setting, can you change the zoom manually and see if this bug still prevails?

Anyhow, as this is an upstream bug, and I have virtually no C++ knowledge, I can't really fix this. I would prefer not to mask the package as a result of this, as it is still usable. I, for one, have been using the package for about a year, and have not yet experienced this problem.

[Comment 4 Sideris Michael 2007-10-21 10:44:07 UTC]

Actually it crashes on any way you view it, at any zoom, no matter what. If you move with page down/up or the arrows, it simply crashes. Mouse wheel scrolling, surprisingly, works and this is what makes me wonder even more regarding the nature of the problem. Anyway, of course you shouldn't mask it if the problem is not generic and I understand that you cannot fix it yourself, as I can't too. I will also try without the nvidia driver, using the nv one, maybe that causes the problem, who knows.

[Comment 5 Stefan de Konink 2008-03-26 01:21:41 UTC]

I had the same problem but only on PPC. I have downloaded the SVN tree compiled it and the error seems to be gone :)
