What do they mean and how to get rid of them?
Every time I launch any GTK based tool I get near unlimited warnings
like that. GTK just loves to spew meaningless messages. If the tool
is working for you, just ignore them. If it breaks somehow and you want
to submit a bug report, then they might provide extra info to be
included in the bug report.
As far as I know, the only way to get rid of them is to redirect
stderr to /dev/null.
