@ az_ua,
tazpkg -l | grep slitaz-configs
gives
slitaz-configs 5.5.4 base-system
and not slitaz-configs 5.5.2 base-system
slitaz-configs-base 5.5.4 base-system
I gave you a wrong information: trash an HD problems don't exist on a frugal install, just on full install.
I tested last ISO (20140817) -> same as 20140815, no trash and no HD in PCManFM with full installation.
Below, 2 screenshots.
The first, 4in1-140804.png is last ISO that doesn't have any problem (except Application Launch Bar but I agree with Aleksej, I think it' a bug in PCManFM).
The second, 4in1-140815 shows the problem I meet with the two last ISOs.
I've made my full installation with the 4in1 iso; I'm going to see if problem exists with installation from core ISO.

EDIT: No chance with the last ISO of the day.
