Autobuilder should be reporting errors to the error report server
http://git.yoctoproject.org/cgit/cgit.cgi/yocto-autobuilder/commit/?id=c3e95f677006b17274668e63612814e67769731c
This is verified. The AB is now sending the errors to the error reporting server at the end of each buildset. Cheers, Ionut C
