kdcache sparse files overrun disk quota

Hi there,

KDE4 creates cache sparse files only some kb in size but apprearing to be app. 100MB in size. Unfortunately this also fools the disk quota. On our terminal server we have a disk quota for every user of 200M.
So users quotas are exhausted although the disk space is not really needed.

Is there a possibility to disable kde caching?
Is there a possibility to reduce the size of the cache?
Is there a possibilily to use normal files instead of sparse files?
