Bug #19642: "Could not find class" hiccups *often* once after manifest/module 
changes

Hi,

if I change a file in a module or manifest directory this *often* results in 
errors, mostly of the following kinds

 * Could not find class <class> for <node> on node <node>

 * Cannot find definition Class on node <node>

These errors occur when puppet modules/manifests are changed - but it happens 
only once. If it happens affected puppet agents will use their cached catalog 
once. **The next time these agents request a catalog it is compiled flawlessly 
and everything will work like a charm** - all errors are gone. Problem is we 
have agents with complex catalogs. Their catalog runs can take up to over a 
minute and so the time it takes for a change to be applied will then be doubled 
to take up to 2 or even 3 minutes.

Usually changes of modules/manifests are performed by "git pull". But it's easy 
to reproduce these error messages by simple "touch" operations. Here are some 
interesting log observations and their [commonness]. Yes AFAICS they always 
appear in triplets. It rarely happens that there are no problems at all after a 
modification.

      [often] puppet-master[12498]: Could not find class <class not even part 
of module dispatcher> for <node not even affected by module dispatcher> on

Affected classes and nodes seem to be randomly chosen. I've got no idea if this 
is a bug or some kind of misuse/misconfiguration. Hope somebody can help. 
Thanks!
