It happened many times, and I think that previous crash files aren't saved, so this crash file might not be compatible with the files I sent before.

Thank you for your bug report. I reported this upstream.

I have run into this bug as well. It seems that this bug only occurs in the following scenario:

- You have "Allow Xfce to manage the desktop" turned on in "Desktop Preferences"
- You have the "Desktop Icons" option set to "None" (don't display desktop icons)
- xfdesktop was started with these settings

Interestingly, if you turn "Desktop Icons" to "None" after xfdesktop has already loaded,
right clicking will work. This suggests that some internal state necessary for the right
click menu to work is only getting set up when configured to display icons on the desktop.

Upstream request :

"I'll need to know the contents of the ~/Templates/ directory."

Could you please give us the exact steps to reproduce this bug ? Upstream needs them.

This seems to be Xubuntu only :

"Regarding the bug summary - 'common_desktop_menu()' doesn't exist in stock
xfdesktop. This sounds like this is due to an Ubuntu-specific patch. Please
ask the reporter to try to reproduce the bug with vanilla xfdesktop sources
from xfce.org. If it's still there, reopen this bug."

Lionel could you please have a look ?

Yes, that's xubuntu-specific: debian/patches/02_show_context_menu.patch contains this function. According to the changelog, it seems that with it xfdesktop context menu will show up if the user right-clicks anywhere on the desktop (versus only on an icon for a vanilla xfdesktop). So this cant' really be disabled without a loss of feature...

Marking this as triaged as we now know what cuases the crash.

workaround: does not crash if "Behaviour/Desktop Icons" set to "File/launcher icons".

Thanks - that fixed it!

I'm also seeing this behaviour.

Alternative workaround: Settings Manager -> Desktop ->enable "Show desktop menu on right click". Looks like the segfault occurs when all the menus which could be displayed have been turned off.
