The SYS:Utilities/PrefsObjectsEditor tool seems to work fine - unless you run MemGuard, which reveals a hit. This is the relevant Sashimi output:

And what did you do to achieve that output?
Every command/keystroke, please.

@tonyw

Very simple:

- I booted into Workbench.
- Executed Memguard and Sashimi.
- Opened the SYS:Utilities drawer and clicked on the PrefsObjectsEditor icon.
- Here comes the hit.

Posted: **Mon Feb 11, 2013 1:32 pm**

So, has anyone actually tried to run MemGuard and reproduce the hit? I've recently reported MemGuard hits in SketchBlock and NetSurf - in both cases they were real (and have since been fixed by the authors) so I don't think I'm just imagining things.

@Trixie

I just tests it on my latest beta / peg2, and just dbl-click on icon even bring not memguard hit, but classic GR instead

!

Hidden Text - Click to Show :

I.e. i just run it after hard reboot and its happy crashes.

Another funny momment, that its never crashes if i run it from context menu, but crashes all the time if i run it from icon on wb. If i change in icon of prefsobjecteditor from "workbench" to "shell" , then it runs fine. So, seems something wrong with parsing of WB args or so ?

I will ask now in mailing list if anyone can reproduce, and then will make a BZ

@Trixie
BZ done, #8256 with your and my crashlogs

@kas1e

Thank you! Now let's hope someone actually looks at what the problem might be.
