title: Eclipse PyDev Breakpoints Show an Different Icon and Don't Work
body: <p>Breakpoints have been working for me for many weeks, but yesterday they stopped working.  When I create a breakpoint icon shown is not the usual magnifying glass, but instead is the magnifying glass with a line through it.</p>
  
  <p>I tried the suggestions in <a href="https://stackoverflow.com/questions/9486871/pydev-breakpoints-not-working">pydev breakpoints not working</a></p>
  
  <p>E.g.</p>
  
  <pre><code>import sys
  print 'current trace function', sys.gettrace()
  </code></pre>
  
  <p>which reports "current trace function main.PyDB object at 0x101416090>>
  "</p>
  
  <p>I tried accessing breakpoints in another Python project and the breakpoints there have the same problem.  Restarting Eclipse, the Mac and reinstalling PyDev had no effect.</p>
  
  <p>I tried installing PyDev in another Eclipse installation on my Mac and breakpoints in Python work find there.  </p>
  
  <p>Any ideas, anyone?</p>
