The process for the file protocol died unexpectedly.

Error - KDesktop: The process for the file protocol died unexpectedly.

Getting this at login (following cold boot) if there are a few windows or tabs left open from previous session.
This is not about windows opened by root - regular windows opened by user. Also, not about CD/DVD windows when media was removed.
The problem is not 100% repeatable - maybe 1 in 5 to 10 logins.
When the error happens there are no icons on the desktop.

Found a few suggestions on line (even in this forum: Error msg: The process for the file protocol died - openSUSE Forums) but none helped.

In summary the suggestions point to:
A - corrupted or too large desktop background file = had same problems with the standard background or none at all.
B - slow CPU = Intel Quad Core @ 3.6GHz I think should do.
C - limited system or video RAM = 4GB DDR3 1700 & 9800GTX+ 512MB.

I also found some information regarding similar KDE bugs (in older versions) but no clear solution there either.

I. Make sure to close everything before shutdown.
II. If the error happens, I could log off and log back in or create a new text file on the desktop (makes all icons reappear).

Any suggestion appreciated.

OS: Linux x86_64
System: openSUSE 11.1 (x86_64)
KDE: 3.5.10 “release 33.2”

Exactly the same problem here and exactly the same workaround - a restart is simplest!

Nice to see loads of help and suggestions - not!!

My system is Suse 11.0 on an oldish PC, but it used to work fine.
I have seen a suggestion to force a reinstall of Konqueror as KDesktop is a part of this, but why then does it sometime start and sometimes not?

Let me know if you find an answer to the problem and I will do likewise.
