Googling reveals that this is a general problem with gtkmm applications (such as easystroke and gnome-system-monitor) that somehow depends on the theme used:

This is probably not a gtkmm bug either, but I've assigned it to gtkmm so that the gtkmm maintainer can investigate the problem.

Adding properties to GObject types does not seem like something that a theme should be doing. It doesn't seem like a problem in gtkmm. gtkmm derives GObject types but so could any application.

I suspect that the crash is actually because the theme code doesn't check for the error, but I'm not interested in looking at its code. What theme is this?

[Stepan Martiyanov (symsym)]

New wave theme.

[Stepan Martiyanov (symsym)]

Same error appears in Human theme.

[Murray Cumming (murrayc)]

symsysm,
> Same error appears in Human theme.

With any application or just easystroke? Does it cause a crash (abort) with the Human theme?

[Stepan Martiyanov (symsym)]

Easystroke not start only. I've tested with "New wave" theme and got same error.

[Murray Cumming (murrayc)]

So I guess this is just a bug in easystroke itself rather than any general theme or gtkmm problem. A backtrace from gdb, maybe with "break g_log" might provide a clue.

Have you tried a different gtkmm application, such as gnome-system-monitor?

[Stepan Martiyanov (symsym)]

$ gnome-system-monitor

** (gnome-system-monitor:2467): WARNING **: SELinux was found but is not enabled.

I'm not sure that problem in it, but when I removed gnome-globalmenu then easystroke and gnome-system-monitor are perfectly executed.

[Tom Jaeger (thjaeger)]

Why do people want their linux desktop to look like Mac OS? Disgusting.

In any case, this is not a bug in any package shipping with ubuntu.

[Stepan Martiyanov (symsym)]

Just because it's convenient. I like the minimalism, GlobalMenu saves space on my desktop, and I do not want to see same menus in the windows. Let it be somewhere.
