I also see this in gnome with 11.04 using the latest fglrx driver (11.4). If I run firefox from the command line, go to youtube and then click the full screen icon I get this output:
*** NSPlugin Viewer *** WARNING: unhandled variable 18 (<unknown variable>) in NPN_GetValue() The program 'npviewer.bin' received an X Window System error. This probably reflects a bug in the program. The error was 'BadRequest (invalid request code or no such operation)'. (Details: serial 1119 error_code 1 request_code 159 minor_code 19) (Note to programmers: normally, X errors are reported asynchronously; that is, you will receive the error a while after causing it. To debug your program, run it with the --sync command line option to change this behavior. You can then get a meaningful backtrace from your debugger if you break on the gdk_x_error() function.) *** NSPlugin Wrapper *** ERROR: NPP_WriteReady() wait for reply: Connection reset by peer *** NSPlugin Wrapper *** WARNING:(/build/buildd/nspluginwrapper-1.2.2/src/npw-wrapper.c:2390):invoke_NPP_Write: assertion failed: (rpc_method_invoke_possible(plugin->connection)) *** NSPlugin Wrapper *** WARNING:(/build/buildd/nspluginwrapper-1.2.2/src/npw-wrapper.c:2163):invoke_NPP_NewStream: assertion failed: (rpc_method_invoke_possible(plugin->connection)) *** NSPlugin Wrapper *** WARNING:(/build/buildd/nspluginwrapper-1.2.2/src/npw-wrapper.c:2235):invoke_NPP_DestroyStream: assertion failed: (rpc_method_invoke_possible(plugin->connection)) *** NSPlugin Wrapper *** WARNING:(/build/buildd/nspluginwrapper-1.2.2/src/npw-wrapper.c:2119):invoke_NPP_URLNotify: assertion failed: (rpc_method_invoke_possible(plugin->connection)) *** NSPlugin Wrapper *** WARNING:(/build/buildd/nspluginwrapper-1.2.2/src/npw-wrapper.c:2119):invoke_NPP_URLNotify: assertion failed: (rpc_method_invoke_possible(plugin->connection)) *** NSPlugin Wrapper *** ERROR: NPObject 0x7fe592bcc230 is no longer valid! *** NSPlugin Wrapper *** ERROR: NPObject 0x7fe592bcc230 is no longer valid! *** NSPlugin Wrapper *** ERROR: NPObject 0x7fe592bcc230 is no longer valid! *** NSPlugin Wrapper *** ERROR: NPObject 0x7fe592bcc230 is no longer valid! *** NSPlugin Wrapper *** ERROR: NPObject 0x7fe592bcc230 is no longer valid! *** NSPlugin Wrapper *** ERROR: NPObject 0x7fe592bcc230 is no longer valid! *** NSPlugin Wrapper *** ERROR: NPObject 0x7fe592bcc230 is no longer valid! *** NSPlugin Wrapper *** ERROR: NPObject 0x7fe592bcc230 is no longer valid! *** NSPlugin Wrapper *** ERROR: NPObject 0x7fe592bcc230 is no longer valid! *** NSPlugin Wrapper *** ERROR: NPObject 0x7fe592bcc230 is no longer valid! *** NSPlugin Wrapper *** ERROR: NPObject 0x7fe592bcc230 is no longer valid! *** NSPlugin Wrapper *** ERROR: NPObject 0x7fe592bcc230 is no longer valid! *** NSPlugin Wrapper *** WARNING:(/build/buildd/nspluginwrapper-1.2.2/src/npw-wrapper.c:1973):invoke_NPP_GetValue: assertion failed: (rpc_method_invoke_possible(plugin->connection)) *** NSPlugin Wrapper *** WARNING:(/build/buildd/nspluginwrapper-1.2.2/src/npw-wrapper.c:2163):invoke_NPP_NewStream: assertion failed: (rpc_method_invoke_possible(plugin->connection)) *** NSPlugin Wrapper *** WARNING:(/build/buildd/nspluginwrapper-1.2.2/src/npw-wrapper.c:2119):invoke_NPP_URLNotify: assertion failed: (rpc_method_invoke_possible(plugin->connection)) *** NSPlugin Wrapper *** WARNING:(/build/buildd/nspluginwrapper-1.2.2/src/npw-wrapper.c:2163):invoke_NPP_NewStream: assertion failed: (rpc_method_invoke_possible(plugin->connection)) *** NSPlugin Wrapper *** WARNING:(/build/buildd/nspluginwrapper-1.2.2/src/npw-wrapper.c:2119):invoke_NPP_URLNotify: assertion failed: (rpc_method_invoke_possible(plugin->connection)) *** NSPlugin Wrapper *** WARNING:(/build/buildd/nspluginwrapper-1.2.2/src/npw-wrapper.c:1854):invoke_NPP_Destroy: assertion failed: (rpc_method_invoke_possible(plugin->connection)) *** NSPlugin Wrapper *** ERROR: NPObject 0x7fe592bcc230 is no longer valid!
