<div style="margin-top:0px;margin-bottom:0px;margin-left:0px;margin-right:0px;text-indent:0px;">Ok, I think I understand the problem. The eric debugger backend is assigning its own handler for stderr and stdout in order to communicate their output back to the frontend (it is what you would see in the shell window). By your reopening you take stderr away from it and that causes the issue later on.</div>
<div style="margin-top:0px;margin-bottom:0px;margin-left:0px;margin-right:0px;text-indent:0px;"> </div>
<div style="margin-top:0px;margin-bottom:0px;margin-left:0px;margin-right:0px;text-indent:0px;">Please try it with disabled stderr redirection. You may do this on a project basis (Project->Debugger->Debugger Properties) or more general via the configuration dialog, Ruby Debugger page.</div>
