Hello,
It seems that Local fetcher in bitbake doesn't bother to check for file
existence under some conditions. This will result in obscure build
failures, like:
NOTE: package bluez-cups-backend-3.23-r0: task do_unpack: started
NOTE: Unpacking /usr/portage/distfiles/bluez-utils-3.23.tar.gz

NOTE: Task failed: NOTE: package bluez-cups-backend-3.23-r0: task
do_unpack: failed
(Here Local.localpath() returned "").
I made a patch to catch this. It really needs more testing (who knows,
maybe lack of validation is by design, and it should be put
elsewhere ;-) ), so here's for review. Note the relevant context dumped
in error - it's very important to improve bitbake's diagnostics which
is by now mostly useless from outsider's point of view (and for
non-outsiders it may take hours to debug a problem), if we want to bring
more people to OE.
