Created attachment 2670 backtrace from xfce4-panel Hey Nick, it seems to be a bad problem in tasklist. It crash (with the whole panel) when: - handle is disabled - no window is present in the tasklist (which means at xfce4-panel startup time for example). I guess there's a problem calculating the plugin size, or something. I've attached the backtrace.
Hey Nick, it seems you just released a bugfix release for the panel, but I didn't see a fix for this bug. I'll try it but I guess it's still reproducible. Would you have time to check it? Cheers, and thanks.
This seems fine in 4.7, please reopen if it you still have this >= 4.7
