For me solvable_files.sh fails with

ERROR:  syntax error at or near "base64"
LINE 4: ...mdzdGVjaG5pay9mdy1kdF9LYXBpdGVsMDhfMDFfMjAucGRm, 'base64'), ...
                                                             ^

I'm using pgsql and have groupfolders.

The error seems to occur in the groupfolder branch.

There (line 73) the quoting of the SQL statetment seems wrong to me. It is definitively different than the version for normal users.

After changing the quoting to be similar to the case for normal users, I don't get any errors anymore.
