title: WebStorm failing to start with 'idea.system.path' error
body: <p>I was saving a file earlier and webstorm started throwing errors as I was saving saying the an 'idea' file was read only. It was unresponsive so I killed the process. Aftr I tried to restart WebStorm and I got the following error:</p>
  
  <p>Temp directory '/home/xxxxxx/.WebStorm8/system/tmp' is inaccessible.
  If you have modified the 'idea.system.path' property please make sure it is correct,
  otherwise please re-install the IDE.</p>
  
  <p>I am using Linux operating system. LXDE to be specific. Also I have not tried to re install the IDE as that will be my last resort. Any help with this would be greatly appreciated.</p>
