Redmine

Hi,

I guess I have found a problem in Redmine 2.5.1.

First here the necessary informations:

Environment:
Redmine version 2.5.1.stable
Ruby version 1.9.3-p231 (2012-05-25) [i386-mingw32]
Rails version 3.2.17
Environment production
Database adapter Mysql2
SCM:
Filesystem
Redmine plugins:
redmine_custom_workflows 0.0.4
redmine_egroupware_clients 0.0.2
redmine_steinhart_capa 0.0.1

What happens?

I have made an update from version 2.2 to 2.5.1. Now I have the problem that some of the issues are causing an internal error. All these issues have a history but not all issues with a history are causing that error. According to the stack trace in the production log the method format_value is affected. Here two stack traces:

I have not figured out yet what kind of journal entry in the history is the reason, but I try to get more details ASAP. Anyway, maybe one of the developers might have an idea what is going wrong here.

Best regards
