Comment 38 for bug 890441

Unity is not installed nor compiz (totaly purged)

Looking at .gtk-bookmarks show an issue with dir/subdir names if thet contain "é": translated with % + uppercase letters.
Had Vidéos & Téléchargement dirs , both was malformed into .gtk-bookmarks. Now i've replaced "é" by "e" to avoid this issue. But need to fix it anyway; i'm using fr_FR-UTF8 as page code.

This temporary workaround dont remove the gtk-crital errors into .xsession-errors, get the same but far less numerous.
Nautilus service at early gnome-classic session (without effect) is using ~10 Mib; if the filebrowser is opened then the ram used grows to 14; opening firefox browser then nautilus use around 20 Mib.

 I've taken time to observe how that going on: ram crunching seems have stopped (good news) and the early errors logged to xsession-errors dont have new error added. That said, since i've renamed the faulty dirs names, i get this new error:

** CRITICAL **: enchant_dict_check: assertion `g_utf8_validate(word, len, NULL)' failed

About your request above "gtk3 dbg package", i've looked at synaptic archive list about "gtk3" and dont find -dbg package except for canberra; which one(s) do you need ?

AS a result this nautilus issue seems to be a "language" issue as special letters as "é" are not understood by the system directories. (this system is fully non-stop updated)
