Task Manager crashes after latest update

Those messages are basically informational. If the launchers are not present it then taskmanager just skips over them (or it should at least). Is it actually crashing or just emitting those messages?

It's actually crashing yes. I'm unable to Awn at the moment.

I'll attach a video, so you'll se what's (not) happening.

Please install gdb, libawn1-dbg and run Awn via terminal using `AWN_APPLET_GDB=1 avant-window-navigator`. This should produce more useful crash log.

When trying to start (Launcher/Task manager) , I get the following :

Updated crash log, I ran "AWN_APPLET_GDB=1 avant-window-navigator".

The "`menu_proxy_module_load': avant-window-navigator: undefined symbol: menu_proxy_module_load" bit is just plain odd.

@David: Do you have appmenu-gtk installed? Or did you had it installed and removed it?

Also, could you remove the Preferences applet and see what happens? (+crashlog if it still crashes)

Confirmed as an issue with vala 0.10, the code it generates from dock-manager-api.vala causes seg fault.

A workaround is to remove Preferences applet for the moment.

Sweet. Disabling the Preferences applet works great as a workaround, until next build.. Thanks!

I can now confirm that the bug is fixed in the latest build.
