KDE 4.8.0 plasma-desktop-shell crashes w/ USB disks [Solved]

[lhuser]

Mine did that too. Try turning the notifications off. When that used to pop up, my plasma crashed. After turning it off, it's been fine for days.

I see that KDE 4.8.0 is now in the main repository. I for one am interested in seeing how the general population of Sabayon users will fare with this update. I myself will refrain from updating to what I have found to be a buggy release, for the foreseeable future.

Installed 4.8.0 about 2 hours ago and apart from having to login twice (plasma froze the first time) all has seemed well in that 2 hours.
That is for my AMD 46 system, my x86 is updating at the moment;

Linux haymode 3.2.0-sabayon #1 SMP Sat Feb 11 08:52:29 UTC 2012 x86_64 AMD

Edit
Everything appears OK on the x86 system too.

Further Edit:
I have now had a crash of plasma workspace. It happened when trying to sort out dolphin to be useable and while I had a phone attached to download photographs. The recovery was very quick and I would only have seen the KDE error reporter if I'd turned away for a second.
I have saved .xsession-errors for this session but it's the most unfriendly log and I have no idea what I'm looking for. Are there any specific logs that would help?

Updated completely to 4.8.0 earlier. All very smooth,no problems so far. Have tried mounting and unmounting a selection of USB sticks, drives etc. and run through all my usual procedures with no crashes.
So in short. VERY PLEASED.

Well it was fine again, until there was some "updates" that actually was consisting of KDE 4.7.4, then after reboot, I lost a screen, Gnome and Metacity won't start....

I;m removing all things consisting of KDE from console and will log back in to see if Gnome works so I can finish the rest.

Update: Looks like I've crippled it alot. I didn't want to uprade to Sabayon 8 since everything was working the way I wanted, but looks like I got no choice to now...ah well...looks like there's interesting stuff in version 8, so it's probably time to give it a shot.
I'll install it on my laptop as well, since Chakra's too weird. It's lacking a lot of packages and it doesn't even have Wine and compiling it requires dependencies that it doesn't even have, so I'm not going to go to dependency hell just for that.

Now that I have updated everything, I have the same issue with plasma crashing, on the release version (weekly).
It did not work until I have renemed the .kde home folder.
That's it, KDE strikes again and again.
It happens to me all the time, when I perform a KDE upgrade.
There is one exception, when I have upgraded from KDE 4.7 the last time before 4.8.
Anyway, I will spend a day to redo my desktop settings, which is very unproductive.
Is in really not possible a way to import the previous settings?

[NoSavy]

I've had these sort of problems before on various systems. So now I backup and make copies of the /.kde4/share/config/plasma* files.
I do this immediately I have the system up and running, then when things go awry I just copy them over the existing ones and log in again.

I backup the settings too.
When I compare the old vs the new ones, it's a great difference.
And this is regular, but they should import the old settings in order to avoid the crashes.
Now, I try to find how to import my old desktop setting manually.

#msdobrescu
I've spent many many hours trying to compare the files, cutting and pasting etc. and it has always been nesscessary to copy the complete file. A mystery to me on the exact problem. I'm pretty quick a resetting the desktop now even without restoring the the files.
