Report message

Description of problem:
 - Eclipse crashes after showing auto-complete suggestions. 

Version-Release number of selected component (if applicable):
 - Fedora 20  (with many software packages installed)   
    -- Chrome is installed and is set to default browser.(Version 31.0.1650.63)

 - Eclipse Kepler   (from 'sudo yum install eclipse' repository) 
    Version: 4.3.1
    Build id: 11fc20

 - Mac book air, 2011.


How reproducible:
 - I can re-produce the problem on each run.

Steps to Reproduce:
 1) Open eclipse. 
 2) Write JAVA code which makes auto-completion pop up.
 3) First few times the auto-completion is ok. After the 4th or 5th time eclipse crashes. 
 4) Eclipse can't be used for more than a few minutes. 

Actual results: 
 - eclipse crashes. 

 - "A problem has been reported" pops up with the following message:
 "A problem in the java-1.7.0-openjdk-headless-1.7.0.60-24.3.0.f20 package has been detected and the diagnostic data has been submitted" 


Expected results:
 - eclipse should hopefully not crash


Additional info:
 * Work around is to edit the (/etc/eclipse.ini) and add the following line

    -Dorg.eclipse.swt.browser.DefaultType=mozilla

  (note, the '-' inclusive) 

  As mentioned here:
  http://stackoverflow.com/questions/16282249/eclipse-4-2-juno-crashes-on-ubuntu-12-04-precise

  This stops eclipse from crashing. 

 * Starting eclipse with '-clean' does not resolve crash 
 * Using a seperate work-space does not resolve the crash. 
 * I have re-installed the operating system, but after the re-install, after some time the problem emerges again.


Please note:
 - This is the first time I'm posting a bug-report on Linux products. I apologize for mistakes in advance. Please correct me on mistakes that I make. 
 - I'm not familiar with diagnostic information that is typically attached with eclipse/Linux bugs (I'm a student at university), please let me know what/how I need to collect for additional diagnostics.
