StartProcess instance crashes if chaining is enabled

Hi,
We have noticed that when we initiate a PM using a!startprocess through the sail form & if the process model has activities with chaining enabled to which are taking some time to complete, the startprocess crashes. Our requirement is that we need merge a few documents using this model which takes a few seconds extra & present the link to that document on the sail form so chaining right till the end was needed. We tried to put a work around to this by forking a parallel dummy flow & disable chaining on that, but it didn't help. I saw a similar issue where they were talking about this being a bug. Please let us know if anyone have noticed this issue.
