>Description:
The last update of the www/linux-f10-flashplugin11 (from 11.2r202.310 to 11.2r202.327) and www/nspluginwrapper ports breaks it in Firefox. Playing a video file embedded in Flash make Firefox hang during some seconds and finally display an error about the plugin not responding.

I removed and installed again the plugin with nwpluginwrapper -r then -i, and remarked that the path to the plugin changed from:
Original plugin: /usr/local/lib/npapi/linux-f10-flashplugin/libflashplayer.so
to:
Original plugin: /usr/local/lib/browser_plugins/linux-f10-flashplugin/libflashpllyer.so

Still not works.

I deinstalled both nspluginwrapper and linux-f10-flashplugin and installed again with no avail.

Firefox at the command line spit this errors when trying to play a video:
Plugin Viewer  *** ERROR: NPN_GetValue() wait for reply: Message truncated
*** NSPlugin Viewer  *** ERROR: NPN_InvalidateRect() wait for reply: Message type invalid
*** NSPlugin Viewer  *** WARNING:(/nspluginwrapper-1.4.4/src/npw-viewer.c:1196):invoke_NPN_InvalidateRect: assertion failed: (rpc_method_invoke_possible(g_rpc_connection))
*** NSPlugin Viewer  *** WARNING:(/nspluginwrapper-1.4.4/src/npw-viewer.c:1196):invoke_NPN_InvalidateRect: assertion failed: (rpc_method_invoke_possible(g_rpc_connection))

The last error being repeated again and again.

Hope it helps!
>How-To-Repeat:
Update www/linux-f10-flashplugin11 from 11.2r202.310 to 11.2r202.327 and www/nspluginwrapper from 1.4.4_2 to 1.4.4_2 and launch a Flash-embedded video on Firefox.
