Bug 469299

Description of problem:
When trying to visit http://en.wikipedia.org/wiki/[whatever]  and loading the page in firefox or konqueror the browsers will crash with a SIGABRT


Version-Release number of selected component (if applicable):
glibc-2.8.90-14.i686

(I do not know if this related to what is fixed in -15 or not)

How reproducible:
100% when initially trying to load url above afterwords ok

Steps to Reproduce:
1. load up browser, type in url above, watch browser crash
  
Actual results:
Web browsers crash (you can only reproduce this in either, but you have to have a cold system booted)


Expected results:
Webpage loads corrected DNS lookup ok.

Additional info:
- no nscd cache daemon is being used.
- IPv6 is enabled but no IP configured for interface
 
* Sorry, I don't have firefox debuginfo installed but those symbol addrs can be found in as rawhide is frozen most updates.

Crash from gdb caught:
