741492 - mozharness MercurialVCS throws exception when unable to update to tag

Status: RESOLVED WONTFIX

(Release Engineering :: Applications: MozharnessCore, defect, P5)

Description

[Aki Sasaki (not active)]

This pulled the wrong repo, so the tag wasn't there. However, I'd like to give a clear error message here instead.
