+### Please describe the problem.
+
+When working with git-annex in a folder managed by Dropbox, the folders names in .git/annex/objects/ are mangled by Dropbox. This leads to lost files.
+
+This is not a git-annex bug, but the problem is severe and it would be helpful when git-annex can deal with it somehow. Possibilities are:
+
+* include a warning in documentation (this will be probably found after someone encounters the problem actually)
+* issue a warning when running in a Dropbox managed folder
+* avoid using filenames that differs in case only (this would make git-annex also more robust against corruption i.e. when a repository is copied over filesystems/protocols without filename case support)
+
+### What steps will reproduce the problem?
+    cd ~/Dropbox
+    mkdir test_annex
+    cd test_annex
+    git init
+    git annex init "test_annex"
+    cp ~/somefiles/* .
+    git annex add *
+    # wait for Dropbox to upload and mangle folder names in .git/annex/objects/
+    find -L . -type l | wc -l # print number of broken symlinks
+    git annex fsck # prints all the missing files
+
+
+### What version of git-annex are you using? On what operating system?
+
+3.20130207
+Fedora 19
+
+### Please provide any additional information below.
