Using the fix of bug 114, I imported the stack, and, after a while, navigated through that stack which pops up the following exception:

Fix pushed.
You stumbled upon yet another fragile part of trakem2: reader threads either must wait on writes or throw bogus exceptions (and occasionally paint rubbish in a swing component.)
