One of our documents was given a description containing single quotes. After saving, the description was shown with slashes appended in front of the quotes.
Fixed it for my setup by editing index.php around line 386 and replacing
if( BP_GROUP_DOCUMENTS_SHOW_DESCRIPTIONS && $document->description ){ echo '<br /><span class="group-documents-description">' . nl2br($document->description) . '</span>'; }
with
if( BP_GROUP_DOCUMENTS_SHOW_DESCRIPTIONS && $document->description ){ echo '<br /><span class="group-documents-description">' . nl2br(stripslashes($document->description)) . '</span>'; }
