nnmatveev 2011-04-29 16:31 reporter ~0001730	<?php echo isset($this);//breakpoint here echo isset($this); echo isset($this); try to evaluate expression "$this->property" while staying on breakpoint - it will cause crash. Attempt to access property of any other undefined variable doesn't cause crash(for example $a->property). Related issue from PhpStorm tracker - http://youtrack.jetbrains.net/issue/WI-5525
