Redmine

The error occurs if https://github.com/elexis/elexis-3-core is defined as main repository. If I select a different one, the page opens as expected.

So I guess, that there has to be something within this repository that provokes the resp. error.

Environment:
Redmine version 3.2.3.stable
Ruby version 1.9.3-p194 (2012-04-20) [x86_64-linux]
Rails version 4.2.5.2
Environment production
Database adapter Mysql2
SCM:
Mercurial 3.1.2
Git 2.1.4
Filesystem
Redmine plugins:
redmine_agile 1.4.1
redmine_lightbox2 0.2.7
redmine_mylyn_connector 2.8.2.stable
redmine_xapian 1.6.5

Is there anything else I can provide? Rails etc. was satisfied with bundle install as documented.

What do you mean?
Repository which Redmine use needs to be local bare repository.

Certainly, the given repository is configured in reference to a localy stored bare repository.

The problem is, that I am not even able to delete the repository or edit it

When calling https://xyz.foo.bar/repositories/18/edit for example (which is my config page for this repo), I get

The same goes for delete

I don't know why extra_info had broken.
Try "Repsotiry.find(18).clear_extra_info_of_changesets" from rails console.
Or clear extra_info from MySQL console.
