Reporter:  cunger     |       Owner:           
    Type:  undecided  |      Status:  new      
Priority:  minor      |   Milestone:  undecided
 Version:  0.8.2      |    Keywords:           
----------------------+-----------------------------------------------------
 Summary:
 After upgrading master and slaves to v0.8.2/ twisted 10.2.0 BuildStep-logs
 do not seem to be accessible from the waterfall page. A custom buildStep
 for example class raises an exception in 'createSummary' (see below slave
 exception)

 Steps to Reproduce:
 n/a

 Expected Results:
 Logs should be accessible from the waterfall page.

 Actual Results:
 Each request for a log from the waterfall page raises below excption in
 the master's log, and the http request times out.

 Regression:
 Downgrading to twisted 8.2.0 solved the issue

 Notes:
 System Configuration:
 Mac OS X Server 10.5, python 2.5, Twisted 10.2.0
