Update error: There are modified or conflicting files in the repository

Basically on all buildbots.
https://open.cdash.org/index.php?project=ParaView

It seems better, but sometime cdash does not report anything, and I see this in buildbot right now:

100% tests passed, 0 tests failed out of 10
Label Time Summary:
ParaView    =  78.78 sec*proc (10 tests)

@ben.boeckel do you know what’s up?

This sounds like a CDash thing. I’ll let Zack know.

Update: email sent to sysadmin and Zack

As for the update errors, that is odd. Buildbot tries really hard to make the source tree pristine. If it persists, I can check it out later.
