I'm not quite used to debugging compiled programs. Running with Valgrind doesn't allow the plugin to show, though there is some frantic CPU activity for a while. Valgrind log attached. The GDB shell script seems to break the panel startup, but I attached the log and used script. I'll tweak that later this week, but if you know why the panel now seems to break, that would help. > Is there some kind of a scheme, something you're doing (network > related for example) when it crashes? > Not that I've noticed, but it might be because my MPD server isn't always online, and sometimes skips through all the tracks in a playlist quickly (this is because the music partition isn't always mounted).
