I selected "diff this changeset with PREV" on a file that had been added in the current changeset. Obviously there is no previous version to diff against, but failing with an Svn::Error::FsNotFound exception isn't exactly graceful. ;)

We're running Warehouse 1.1.7. Below is the error message and trace:

Svn::Error::FsNotFound in Changesets#diff

Showing changesets/diff.html.erb where line #6 raised:

subversion/libsvn_fs_fs/tree.c:690 File not found: revision 71564, path '/path/to/my/file'

Extracted source (around line #6):
