> I was running BleachBit to clean out unnecessary files on my machine.

Files under /var/tmp (including /var/tmp/kdecache-$USER, where the various
KSharedDataCaches live) are not unnecessary in general.

If you want to remove them, it is safe to simply unlink the file, such as with
the 'rm' command or by deleting them from Dolphin. It's is *not* safe to run
BleachBit on these files unless you do so from outside of KDE, or unless you
ensure that BleachBit is configured not to try to shred or overwrite files for
privacy before deleting them.

If you can reproduce this bug without intentionally destroying the cache data
for the running desktop then please reopen the bug. It would be best to ensure
BleachBit stays out of /var/tmp and other important system paths however.
Comment 4 Andrew Ziem 2011-05-23 20:23:35 UTC 
Next release of BleachBit after version 0.8.7 includes whitelist for /var/tmp/kdecache-* , and in the future, please report BleachBit bugs to https://bugs.launchpad.net/bleachbit/
