Loosing Plasma config on every other update

[Sebastian Trüg]

Hi guys,

running on trunk I loose my Plasma configuration  on every other svn
update. The only exception is the main panel which remains. All the rest
is back to defaults or worse - by worse I mean that I end up with no
widgets at all.
So my only questions are: is this a known problem? Is this simply due to
the fact that I run trunk? Can I do anything against it? Can I maybe
recover the old config?

Thanks a lot,
Sebastian
