Find crashes tracker when editing query

[cebif]

Click on the middle box in find to choose attribute. I type the name contains into the contains box then click the search button. After the list of files appear in tracker, I click on File/Edit Query. A crash occurs. Expected results should be show the find window to change the word or words typed, file type etc. If I leave it at the default "by name" instaed of "by attribute" then type my search word Click search After the list of found files comes up in the tracker Click on File/Edit Query There is no crash in this case. The crash only seems to occur when searching by attribute. After the crash all the icons on the desktop have gone but the deskbar is still showing. I have to "ctrl alt delete" and click restart desktop for them to reapear. This is reproduceable every time. I was testing with hrev19960 on a Beos partition Here is the trace from a crash:

Can you provide a backtrace ? (write "bt" in the debugger, then press enter)

Bugfix: Window() seems to be null in the error case

Thanks for the patch! It's fixed in hrev22102; BWindow is now always checking if BAutolock succeeded, that's why Tracker got away with this bug on BeOS (it now would on Haiku as well).
