Same problem compiled under Ubuntu 9.04 32bit or 64bit.

All you have to do is start a new default application, drop TVirtualStringTree or TVirtualDrawTree component on form, build/run app and then try to close app normally (not Stop within Lazarus).

GDB gives me this info:
TGtkWidgetSet.DeleteObject GdiObject=B706B500 gdiBrush is still used. DCCount=2

DC: B6F886B0 nil

[TGtkWidgetSet.Destroy] WARNING: There are 10 unreleased DCs, a detailed dump follows:
