Unable to upload template

[BadMisterFrosty]

I am having trouble uploading a template. It appears that the program is having trouble getting sudo. I have confirmed that the redmine user (that passenger runs redmine as) is able to sudo. In the logs below, you can see slightly different errors for "Add new" and "Replace Existing" options. Any ideas?

Note: Upon further investigation, this appears to only be happening with custom issues. I was able to successfully upload a template for a "Bug". Maybe there is a problem with the following line.

tracker = Tracker.find_by_name(params[:tracker])

Note 2: More investigation showed that this only affects Trackers that have a space in their names. e.g. "Action Item" vs "Bugs". Does the find_by_name parameter need to be quoted or something? I confirmed this by renaming "Action Item" to "ActionItem" and it appears to be working now.
