Please describe the problem:
System log viewer does not display an horizontal scroll bar at the bottom of the
window, so the contents of a log file cannot be scrolled right or left when the
size of displayed lines do not fit in the window.

Steps to reproduce:
1. Open System Log Viewer.
2. Display a log file.
3. There is no horizontal scroll bar.


Actual results:
I cannot see long lines in log files. They are cropped.

Expected results:
An horizontal scroll bar should be displayed.

Does this happen every time?
Yes.

Other information:
No.
