Cannot read property 'c' of null

I guess it happened when I cliecked on Dashboard of a very new but not empty project.

Unexpected Error JavaScriptException: (TypeError) stack: TypeError: Cannot read property 'c' of null at Object.l3c [as Cf] (http://myserver.de:8080/kunagi/scrum.ScrumGwtApplication/BD1A9917D8AB84245FAB4FD05A0EE760.cache.html:5614:6342) at E$b (http://myserver.de:8080/kunagi/scrum.ScrumGwtApplication/BD1A9917D8AB84245FAB4FD05A0EE760.cache.html:5009:138) at D$b (http://myserver.de:8080/kunagi/scrum.ScrumGwtApplication/BD1A9917D8AB84245FAB4FD05A0EE760.cache.html:5027:37) at Object.M$b [as Df] (http://myserver.de:8080/kunagi/scrum.ScrumGwtApplication/BD1A9917D8AB84245FAB4FD05A0EE760.cache.html:5602:7229) at N3b (http://myserver.de:8080/kunagi/scrum.ScrumGwtApplication/BD1A9917D8AB84245FAB4FD05A0EE760.cache.html:4749:65) at M3b (http://myserver.de:8080/kunagi/scrum.ScrumGwtApplication/BD1A9917D8AB84245FAB4FD05A0EE760.cache.html:3857:64) at N3b (http://myserver.de:8080/kunagi/scrum.ScrumGwtApplication/BD1A9917D8AB84245FAB4FD05A0EE760.cache.html:4749:93) at M3b (http://myserver.de:8080/kunagi/scrum.ScrumGwtApplication/BD1A9917D8AB84245FAB4FD05A0EE760.cache.html:3857:64) at N3b (http://myserver.de:8080/kunagi/scrum.ScrumGwtApplication/BD1A9917D8AB84245FAB4FD05A0EE760.cache.html:4749:93) at M3b (http://myserver.de:8080/kunagi/scrum.ScrumGwtApplication/BD1A9917D8AB84245FAB4FD05A0EE760.cache.html:3857:64) at N3b (http://myserver.de:8080/kunagi/scrum.ScrumGwtApplication/BD1A9917D8AB84245FAB4FD05A0EE760.cache.html:4749:93) at M3b (http://myserver.de:8080/kunagi/scrum.ScrumGwtApplication/BD1A9917D8AB84245FAB4FD05A0EE760.cache.html:3857:64): Cannot read property 'c' of null

The JavaScript error does not help. Do you have the server log for this problem? Did you see it again?
