Empathy does not write chat-log-files when TpLogger under ~/.local/share is a symbolic link

Since i want my Conversations synchronized, i have setup dropbox with some folder ~/Dropbox/IM/TpLogger and created a symbolic link under .local/share/TpLogger that points to ~/Dropbox/IM/TpLogger.
This worked in the past, but stopped working at some point in the past.

when i have empathy running and delete this link (by moving it to TpLogger.old for instance) a new TpLogger Folder is created and my logs are stored.

when run empathy with the TpLogger being a link and send/receive a message i get the attached log, where the interesting part is at 167:
(telepathy-logger:11067): tp-logger-CRITICAL **: _tpl_log_manager_add_event: logstore name=TpLogger: Couldn't open log file: /home/cnlpete/.local/share/TpLogger<email address hidden>/20111111.log. Event may not be logged properly.

however, running touch, less or nano on exactly this file, i can access and edit.

I did antother test, where i put a Folder TestDir under .local/share (cd ~/.local/share && mkdir testdir) and have a symbolic link with this target (ln -s testdir TpLogger).
Then trying to send a message results in the following debug-block:
(telepathy-logger:11551): tp-logger-DEBUG: tpl_entity_new: Self id: <email address hidden>/cnlpete, tok: (null)

(telepathy-logger:11551): tp-logger-DEBUG: _tpl_log_store_sqlite_remove_pending_messages: - pending_id: 12

but the folder does not get created!
sending another message results in exactly the same debug-output, where empthy (or tplogger) tries to create the folder but does not get created...
