2 bogs please report a mayor and minnor

[Dokuro]

hello can't post the bug, sorry

the mayor one happends when a crash report is about to be generated on
a crash while showing the overview if the crash is about to happen and
the overview is activated the gnome shell crashes for good with a
woops and no rebot helps

the minor one is that while copying files the paste command on the
left mouse menu seems unactivated but it can be used.
