Starting from revision 19044, when i put a TVirtualStringTree control in
a form the IDE crashes (see attached log). I could not reproduce with
other controls and i'm not sure if the problem is in the changes
introduced in 19044 or if just revealed a TVirtualStringTree bug.
The VTV code can be obtained from:
https://lazarus-ccr.svn.sourceforge.net/svnroot/lazarus-ccr/components/virtualtreeview-new
It requires LCLExtension package:
https://luipack.googlecode.com/svn/trunk/lclextensions
Any help is appreciated.
