At least reproducible in combination with firefox-16.0.2-1.fc17.x86_64: With the npsoplugin enabled (see <http://wiki.documentfoundation.org/Npsoplugin>): 1 open a ODF file in Firefox (so that soffice is started in background and displays the document inside Firefox), 2 in parallel, start "soffice --writer" (see bug 57056 for the requirement to pass --writer; the call returns early but shows the Writer document via the soffice started in background) 3 close the ODF tab in Firefox (but keep Firefox open) 4 close the Writer document from step 2 5 again open an ODF file in Firefox: the tab stays white, only shows the document after reloading the current page.
