Dan Haywood commented on ISIS-620:
----------------------------------
A further remark. The steps in the original scenario doesn't cause an
exception for me:
* load fixtures
* open arbitrary todo
* click edit, change description, click save
* again, click edit, change description, click save
HOWEVER, if I then do a "back button" after all the above, then I get an
exception, with the stack trace (below) indicating its the bookmark panel. If
that's the case, hopefully easily enough to isolate.
