title: Application crash libc: Fatal signal 11 (SIGSEGV), code 1
body: <p>I have next fatal error:</p>
  
  <pre><code>A/libc(30888): Fatal signal 11 (SIGSEGV), code 1, fault addr 0x8 in tid 30897 (FinalizerDaemon)
  </code></pre>
  
  <p>I have no ideas what went wrong. Perhaps this is due to <em>RxJava</em>, <em>GsmTaskorService</em> or <em>Greendao 3</em>. My stacktrace below:</p>
