When using the webapp to view the source of of files with '+' in their path, the operation fails with a popup stating 'The resource could not be found.'
When this happens, a line similar to the following appears in the logs (this request was for a file named '1+1.txt'):
[qtp1967563673-18] WARN sonia.scm.api.rest.resources.BrowserStreamingOutput - could not find path 1 1.txt
It appears that somewhere along the line, the '+' got stripped from the path.
This is an RPM installation on CentOS 6.4, migrated from a standalone install according to https://bitbucket.org/sdorra/scm-manager/wiki/RPM%20and%20DEB%20packages
