I'm quoting from user "jwhendy" at https://bbs.archlinux.org/viewtopic.php?id=119122
 
I'm posting this here because his fix worked for me.

Wow -- what a surprise to find that a bug report was already filed for my find quoted below!

A new version must have reverted my fix, as this just started happening again. Opening downloaded pdfs in Chromium correctly opens in my pdf reader set via xdg-mime, however upon closing that pdf viewer, Firefox will try and open the file as well. Fixing the script as shown at the linked Arch Linux forum post does, indeed, work for me.

This was fixed along with bug #32487

@Rex Dieter:

That "duplicate" was fixed with a commit in Dec 2010 -- I find it odd that this would be a duplicate since it's occurring 7 month later. This is certainly not fixed in all cases for me. I have also verified that my version contains the fix from this Dec 2010 bug:

line 420 in /usr/bin/xdg-open
,---
| local file="$x/applications/$default"
`---

some other pertinent information/settings verification:
,---
| $ xdg-mime --version
| xdg-mime 1.0.2
|
| $ xdg-mime query default application/pdf
| evince.desktop
| 
| $ evince --version
| GNOME Document Viewer 2.32.0
`---

Steps:
1) google "test pdf"
2) download first hit: www.education.gov.yk.ca/pdf/pdf-test.pdf
3) open from browser
4) opens in evince
5) quit evince
6) firefox opens up asking me what I want to do with it
7) replicate from command line:

,---
| $ xdg-open pdf-test.pdf 
| /usr/bin/xdg-open: line 419:  6617 Segmentation fault \
|    $command_exec "$1"
`---

Fix:
1) edit /usr/bin/xdg-open
2) edit line 425 from:

,---
| $command_exec "$1"
`---

to:

,---
| eval `"$command_exec" "$1"`
`---

I'm open to other suggestions... but just want to definitively state that this has not been fixed for me. I'm open to other suggestions regarding settings on my system or WM/DE or something else that might be doing this.

For potential assistance:

,---
| $ uname -a
| Linux Macrophage 2.6.39-ARCH #1 SMP PREEMPT Sat Jul 9 14:57:41
| CEST 2011 x86_64 Intel(R) Core(TM)2 CPU T7200 @ 2.00GHz 
| GenuineIntel GNU/Linux
`---

Please ask for any other information.

Sorry, wrong dup, should've been bug #30453

re-confirmed this should be fixed with commit a616912e48b7ff1d908852739d16525df79471b9

See:
http://cgit.freedesktop.org/xdg/xdg-utils/commit/?id=a616912e48b7ff1d908852739d16525df79471b9
