Tracker/BShelf crash on clicking replicant dragger menu

[elvencode]

Tested on build 23925

when clicking on the replicant grip 2/3 times moving a little the mouse the menu (or probably the start of rendering a selection box in the desktop) trigger a crash of the Tracker. It doesn't show up always but quite frequently.

edit: since hrev29949, it can only happen with a custom dragger popup menu. (cf. BeBook)

Can you provide a stack trace ? ("bt" inside the debugger window).

I remember seeing that one quite frequently a few months ago, can't reproduce here, hrev29443 (vmware and real 2 cpus).

To elvencode and others: Can you check again?

Still present in 29448. Tested in Vmware Player 2.5.0 (Ubuntu 8.10, 32-bit), using the replicant handle of DeskCalc.
Excerpt from serial output attached.

aldeck: you fixed something possibly similar some months ago, in hrev28089. Just thought I'd mention.

luroh: Ok, i can reproduce, thanks for testing. It happens when you drag the BDragger while the popup menu is showing. There's a locking issue when BDragger tries to archive its popup menu (for the replicant drag message). Will look into it.

fixed in hrev29727

reopening, there's sometimes a problem when unlocking the popup menu's window, although, since hrev29949, it can only happen with customized dragger popups.

made the summary/description a bit more exact
