Description of problem:
gvfsd-archive crashes when I try to open an ISO image. Reproducibility might help to identify an underlying problem in gvfs, it seems that the way how it crashes is similar to many other reported bugs. 

Version-Release number of selected component (if applicable):
gvfs-1.6.4-3.fc14

How reproducible:
Always.

Steps to Reproduce:
1. Download http://redhat.lsu.edu/dist/5.2/iso/redhat-5.2-i386.iso (487MB :-( )
2. Try to open the image: (a) nautilus, double click on the icon or (b) run "/usr/libexec/gvfsd-archive file=./redhat-5.2-i386.iso".
3.
  
Actual results:
gvfsd-archive crashes.

Expected results:
The ISO image is mounted.

Additional info:
The problem always starts in the function gvfsbackendarchive.c: create_file_tree(), where the function call archive_read_next_header() returns ARCHIVE_FATAL (-30) and the gvfs is not able to terminate itself properly. It looks like a race condition is involved, threads are not synchronised in the final stage and the result is an attempt to dereference some NULL pointer.
I suspect that another problem is in libarchive-2.8.4-1, the ISO image can be extracted using the file-roller or locally mounted; however the library behaves consistently and gvfsd-archive should cope with that.

Comment 2 Fedora End Of Life 2012-08-16 20:52:25 UTC
This message is a notice that Fedora 14 is now at end of life. Fedora 
has stopped maintaining and issuing updates for Fedora 14. It is 
Fedora's policy to close all bug reports from releases that are no 
longer maintained.  At this time, all open bugs with a Fedora 'version'
of '14' have been closed as WONTFIX.

(Please note: Our normal process is to give advanced warning of this 
occurring, but we forgot to do that. A thousand apologies.)

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, feel free to reopen 
this bug and simply change the 'version' to a later Fedora version.

Bug Reporter: Thank you for reporting this issue and we are sorry that 
we were unable to fix it before Fedora 14 reached end of life. If you 
would still like to see this bug fixed and are able to reproduce it 
against a later version of Fedora, you are encouraged to click on 
"Clone This Bug" (top right of this page) and open it against that 
version of Fedora.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events.  Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

The process we are following is described here:
