3MB Memory Leak in KDrive Xfbdev

[vrushali shinde]

In addition to information below, I also get get following error when
closing VT "Cant deallocate console..." Can  this error contribute to some
or all of the 3M memory leak?
Please let me know if anyone has got any clue about this  or have faced
simlar issue.
Again thanks to all.
