I installed evince on my Arch Linux system as a PDF reader, and everything was fine for a while. And then I installed GIMP. Since then, PDF files have been opening in GIMP. I've tried reinstalling evince, I've tried editing ~/.local/share/applications/defaults.list , I've tried editing /usr/share/applications/mimeinfo.cache, but PDF files still open in GIMP by default.

What desktop environment (Gnome, KDE, XFCE, ...) are you using? – Benjamin Bannier Jul 30 '10 at 20:58
What DE are you using (if any)? [OOPS!] – dag729 Jul 30 '10 at 20:58
How are you opening the PDF? Nautilus, command-line, browser, etc.? – Matthew Flaschen Jul 30 '10 at 20:58
I am using GNOME. (stupid 10 char limit) – Macha Jul 30 '10 at 20:59
+1 for the "completion" :D – dag729 Jul 30 '10 at 21:00

A bit of further research found that the offending file was ~/.local/share/applications/mimeapps.lst

Nice one! Anyway...what desktop environment are you using? – dag729 Jul 30 '10 at 20:59
GNOME, but the link applies to KDE, so they seem to be the same in this regard. – Macha Jul 30 '10 at 21:03
thanks for answer and question. i encountered this very problem lately but was to lazy to look into that matter. done now :) – matthias krull Jul 30 '10 at 21:47

I found that Firefox uses the XDG standard, so using the XDG command line apps to set default applications solved the problem for me.

$ xdg-mime default evince.desktop application/pdf

This tells anything using XDG to use Evince to open application/pdf files.

There's more info where I found this, on the ArchLinux wiki.
