Incompatibility with fugitive.vim

[hanst99]

I'm not sure what it is, but something about haskellmode breaks fugitives :Glog command - git log is still run, but the quickfix list isn't populated with previous revisions anymore and the current file isn't replaced with the last commit. Does haskellmode do something weird to the quickfix list?

It also breaks Ggrep location list, my workflow is :Ggrep "something" and then [q or ]q to jump between found strings.
