Iceweasel has been running okay on a Debian Jessie desktop for a long time.
Lately, it keeps hanging. It was noticed that the following message appeared in an xterm window : ###!!![Parent][DispatchAsyncMessage] Error: PLayerTransaction::Msg_ReleaseLayer Processing error: message was deserialized, but the handler returned false (indicating failure). What does the above message mean ? Is it related to Iceweasel hanging ? There is no problem with the internet connection since another browser works okay.
