Comment 1 Thomas Lübking 2010-07-19 22:14:08 UTC
Nearly everything (!) crashes when your HDD is entirely full, possibly including the kernel (since it looses the ability to swap out memory, at some point you'll get memory corruptions everywhere)

The particular bug is in libplasma/kimagecache, failing to cache a rendered pixmap - but i heavily doubt this is in scope...

(Sidenote: to keep your system in decent state you should keep about 10% of the HDDs unused to allow restructuring, filesystem cleanups etc.)
