Description of problem:
I've noticed we're getting a fair number of tasks which hang with a status of "Post-processing downloaded file".  These tasks all have the following in common:
a) they are a local file and were submitted via "Custom Core Location"
b) they are gzipped files

It seems if you manually gunzip the file, then submit via "Custom Core Location" it works fine.  I also checked and the gunzip exits with a 0, so it's not the gunzip failing.


Version-Release number of selected component (if applicable):
retrace-server-1.10-1.el6.noarch

How reproducible:
It seems everytime if you submit a gzipped file.

Steps to Reproduce:
1. submit a gzipped local file vmcore via "Custom Core Location" from web interface
2. wait for completion (does not complete)

Actual results:
Stuck at "Post-processing downloaded file"

Expected results:
Either error out or complete properly.


Additional info:
I have an example I will share of a gzipped vmcore vs non-gzipped core.
