Comment 13 for bug 947358

You should look in the Debian folder in the source from
1.9+git20120222-1 in Debian unstable. Specifically at the *.install
files. Compare those to the Ubuntu Version's source. According to
comment #10 the campaign folder is missing from the install file. I
Agree with Asier that the origin of the bug is that exact problem.
Merging from Debian unstable will be easier than fixing it yourself. The
workaround for the current non-working version is to make that folder
manually. However it is not a bug fix, simply a workaround, as it does
not install the contents (if there are any).
