Hi, My Webapp isn't working: $ git-annex webapp error: refs/gcrypt/gitception+ does not point to a valid object! error: refs/remotes/Beta/git-annex does not point to a valid object! error: refs/remotes/Beta/master does not point to a valid object! fatal: unable to read tree 656e7db5be172f01c0b6994d01f1a08d1273af12 So I tried to repair it: $ git-annex repair Running git fsck ... Stack space overflow: current size 8388608 bytes. Use `+RTS -Ksize -RTS' to increase it. So I tried to follow your advice here and increase the stack: $ git-annex +RTS -K35000000 -RTS fsck git-annex: Most RTS options are disabled. Link with -rtsopts to enable them. I wasn't sure what to do next, so any help would be appreciated.
