<p class="MsoNormal">Oddly, I was communicating with someone about a similar issue, but haven't been able to get to the root cause. Do you have a debug build of ParaView? Would it be possible to get a callstack to when than error message is popped up?<o:p></o:p></p>

is compiled using the Intel 2015 compiler suite. <o:p></o:p></p>
