Guitar Pro 5.2 demo +treeview log

With wine-1.1.44-19-gd2a0188, after installing the Guitar Pro 5.2 demo, then
launching and dismissing the trial nag dialog and initial setup, pressing
Ctrl+B (or going to File -> Browser... menu) brings up a file browser dialog.
Expanding a drive letter, such as C:, shows directory subitems, but an
extraneous ":" item appears at the top of the directory listing also.
Attempting to expand this item causes a dialog box to display complaining of an
access violation, and expanding directory subitems causes the ":" item to also
be added to their respective subdirectory lists. Using native comctl32 makes
the problem disappear, and a +treeview log is attached.
