title: Whats SIGSEGV, Segmentation fault in Qt
body: <p>I have a Qt program which displays the data it receives over UDP.
  It works fine for around 30 seconds but after a while it gives Segmentation Fault and crashes. This 30 seconds is also not fixed.</p>
  
  <p>I used the debugger and got this: </p>
  
  <pre><code>Program received signal SIGSEGV, Segmentation fault.
  0x003c6fd4 in ?? () from /usr/lib/libQtGui.so.4
  </code></pre>
  
  <p>Can anyone tell me where the error might be?</p>
