Description cl 2013-03-21 00:21:42 UTC 
From what I can determine, any script-fu script that allows you to select a gradient, will cause a crash when you attempt to select the gradient. Confirmed with multiple installations of Fedora 17 & Fedora 18.

To duplicate the crash...
1) Start GIMP 2.8.4
2) File/Create/Logos/Blended
3) Click/Select Gradient
4) Click Close

GIMP 2.8.4 crashes with the following error:

*** glibc detected *** gimp: double free or corruption (!prev)

Indeed.
Comment 2 Michael Natterer 2013-03-21 00:40:42 UTC 
This seems to be broken since 2006, doesn't anybody use script-fu?
Comment 3 Michael Natterer 2013-03-21 00:53:55 UTC 
Fixed in master and gimp-2-8:

Power GIMP users are constantly utilizing script-fu scripts and there were no problems selecting gradients in older GIMP versions, including GIMP 2.8.2. This bug appears to be new in GIMP 2.8.4.

Presently, the only solution is to revert back to GIMP 2.8.2 (or earlier).
Comment 5 Michael Natterer 2013-03-21 07:18:54 UTC 
I know people are using script-fu all the time :) It's just absolutely
absurd that this code didn't crash before. Anyway, it's fixed now.
