Tracker crash on context menu (Looper must be locked)

This is hrev52267.

After right-clicking to do some drill-down-navigating I got the attached crash:

debug report

I think this crash may be the same thing. Debug report and syslog attached.

I just got one of these.

I was moving a cloned repo of Haiku's website, from one partition to a bigger one. Used Tracker's drag-and-drop "Move here" menu item into folder "~/SourceCode/".

While that move operation was running, I renamed a different folder inside that "~/SourceCode/".

After that, I attempted to create a new folder. The debugger call happened after I right-clicked in the Tracker's window for that "~/SourceCode/" folder (was trying to reach the "New->New Folder" menu item).

Unfortunately I too have seen this crash before too. It has to do with menu thread trying to access something in the window thread without locking properly. When I tried to implement live menu updating feature a while back I ran into this issue consistently, but I never quite got around to fixing it.

I've seen this crash before to. It seems like when the nav menus (the menu item at the top with the drill down menus) get generated Tracker can get confused and crash sometimes. You say the crash happened when you right clicked in Tracker window, that follows because the nav menus are setup on right-click menus. Unfortunately whatever the problem is it's not consistent enough for me to figure out as it is only happening in some circumstances and then not again. Tracker crashes, it restarts and the problem doesn't return with nav menus are working again.
