sitecore8 - Sitecore's "Links" button doesn't work because of a null-reference exception -


i trying see item's linked items. doing on client's content management server. when click on navigate -> links, nothing happens. error in javascript console:

http://sitename.local/sitecore/shell/default.aspx?xmlcontrol=gallery.links&…de-de&vs=1&db=master&sc_content=master&showeditor=1&ribbon.rendertabs=true

failed load resource: server responded status of 500 (internal server error)

here's see in sitecore logs:

38424 19:09:30 error application error. exception: system.web.httpunhandledexception message: exception of type 'system.web.httpunhandledexception' thrown. source: system.web    @ system.web.ui.page.handleerror(exception e)    @ system.web.ui.page.processrequestmain(boolean includestagesbeforeasyncpoint, boolean includestagesafterasyncpoint)    @ system.web.ui.page.processrequest(boolean includestagesbeforeasyncpoint, boolean includestagesafterasyncpoint)    @ system.web.ui.page.processrequest()    @ system.web.ui.page.processrequest(httpcontext context)    @ system.web.httpapplication.callhandlerexecutionstep.system.web.httpapplication.iexecutionstep.execute()    @ system.web.httpapplication.executestep(iexecutionstep step, boolean& completedsynchronously)  nested exception  exception: system.reflection.targetinvocationexception message: exception has been thrown target of invocation. source: mscorlib    @ system.runtimemethodhandle.invokemethod(object target, object[] arguments, signature sig, boolean constructor)    @ system.reflection.runtimemethodinfo.unsafeinvokeinternal(object obj, object[] parameters, object[] arguments)    @ system.reflection.runtimemethodinfo.invoke(object obj, bindingflags invokeattr, binder binder, object[] parameters, cultureinfo culture)    @ sitecore.reflection.reflectionutil.invokemethod(methodinfo method, object[] parameters, object obj)    @ sitecore.web.ui.sheer.clientpage.onload(eventargs e)    @ system.web.ui.control.loadrecursive()    @ system.web.ui.page.processrequestmain(boolean includestagesbeforeasyncpoint, boolean includestagesafterasyncpoint)  nested exception  exception: system.argumentnullexception message: value cannot null. parameter name: owneritem source: sitecore.kernel    @ sitecore.diagnostics.assert.argumentnotnull(object argument, string argumentname)    @ sitecore.data.fields.field..ctor(id fieldid, item owneritem)    @ sitecore.shell.applications.contentmanager.galleries.links.gallerylinksform.getlinktooltip(item reference, itemlink link)    @ sitecore.shell.applications.contentmanager.galleries.links.gallerylinksform.renderreferences(stringbuilder result, list`1 references)    @ sitecore.shell.applications.contentmanager.galleries.links.gallerylinksform.onload(eventargs e)

it looks owneritem argument null when creating item field.

this happens several different items—e.g. templates , sublayouts.
