[issue3237] Error -3 while decompressing: incorrect header check

[Danny Tuppeny]

New submission from Danny Tuppeny <danny+hg at tuppeny.com>:

Our build server (CruiseControl.net) just reported the below error when 
trying to pull the latest changes. I forced the build to start again, and it 
seems to have worked (it's still in progress, so can't say for sure, but the 
Mercurial step is marked as completing successfully).


ThoughtWorks.CruiseControl.Core.CruiseControlException: Source control 
operation failed: transaction abort!
