Hi, I'm a TDE user since v. 3.5.13, it's a very good desktop environment as it's configurable, fast and efficient in everyday tasks.
Recently I decided to upgrade my Debian notebook (Dell D430 2x1.33GHz 64bit, 2GB RAM, 60GB HDD) to TDE 3.5.13.2. To do this I formatted entire HDD and installed Debian Wheezy NetInstall (amd64) from USB drive. Except typical problems with black screen in console (Intel 950) everything went OK.
After installing TDE and rebooting it launched normally. I configured it as I like: turned sound notifications off, tweaked window decoration to KDE2, icons to KDE2 and added cut/opy/paste/Terminal here buttons to Konqueror's toolbar, disabled ctrl-alt-del at log in. Installed Geany IDE and KNeMo to see utilization of network connections, activated KNeMo to display icons.
After rebooting it doesn't start properly. It gets to proper login screen, when I log in it waits for few seconds using hard disk, then screen turns black and back to wallpaper, login window appears again. This happens in a loop.
Here's a log from .xsession-errors I pulled from console mode. It looks like segfault appears during setting paths.

What should I do to run Trinity? 3.5.13.1 was running well in this machine.
