how did you install it?

at what point did plasma crash in the process?
Comment 2 Alex Merry 2008-08-22 21:57:24 UTC 
KNS::CoreEngine::install() calls KStandardDirs::locateLocal() with a resource type taken from a KNS::Installation.  This in turn calls KStandardDirs::saveLocation(), which (rightly or wrongly) treats an unregistered resource type as a fatal error.  There doesn't appear to be a way of finding out whether a given type has been registered, though.

Now, I can't see why this would crash with plasma, though, since plasmoids.knsrc uses "tmp" as the resource, which is a special type and so should never result in a fatal error.

a cullen: can you reproduce this crash?  If so, can you attach $KDE_INSTALL_DIR/share/config/plasmoids.knsrc (eg: if KDE is installed in /usr, that would be /usr/share/config/plasmoids.knsrc)?  Also, the output of plasma (which can be got by either doing "grep plasma ~/.xsession-errors > plasma.log" or by running plasma from a terminal) would be useful.
