With CVS as of today (February 13, 2006), Tracker
regularly crashes on popups, such as the context menu
on the Trash can.

I am more or less always using the latest Tracker revision,
but I can certainly not reproduce this on any installation
(neither R5, nor Dano/Zeta).
Try rebuilding the whole Tracker, if that helps. In any
case, what exact OS version are you using?
When did you update Tracker the last time?

I am running 2/20/06 sources and I can confirm that this is
an intermittent bug on Max Edition V3. I am currently
experimenting with the following patch to
BDeskWindow::ShowContextMenu. It doesn't fix the problem,
but I am seeing if it makes it less frequent. Initial
results look promising, but I'm not sure.

BRect mouse_rect(global.x, global.y, global.x, global.y);
mouse_rect.InsetBy(-5, -5);

BRect mouse_rect(global.x, global.y, global.x + 10, global.y
+ 10);
mouse_rect.OffsetBy(-5, -5);

From the looks of the stack crawl, this may be an OS bug.

I can't reproduce this, though I remember having similar
issues when running beos 5 under Virtual PC.
