Description of problem:
When using the WebUI to edit configuration files, the entered configuration file
is truncated.

Version-Release number of selected component (if applicable):
5.0.1

How reproducible:
Intermittent

Steps to Reproduce:
1.Create a configuration channel
2.From the Channel Overview screen, select 'Add Files'
3.On the 'Add Files' submenu, select 'Create file'
4.On the next screen, type a file name and then some file contents in the large
textarea
5. Click the 'Create Configuration File' button

  
Actual results:
The saved file occasionally has the last few characters truncated. For example,
in one of our config files we have:

chage -d 0 root

as the last line.

This is always truncated to:

chage -d 0 r

Expected results:
No truncation should occur

Additional info:
There is no proxy in this configuration and the browser is running on the
satellite itself.

This is happening with short files (<1K)

Workaround is to add a comment as the last line of the file if possible as it
does not matter if this is truncated.
