Well, it actually seems to be projectm that's crashing. It hasn't happened when I don't use the visualization.

This on a few day old kubuntu 12.04 lts install, replacing xubuntu 12.10 (I'd really prefer the lts and kde hasn't changed from 12.04 to 12.10 as much as xfce has). I also had kde-desktop installed, which I liked much better.

The main reason I installed kde and then kubuntu was that lots of my favorite apps (esp. dolphin, clementine and smplayer) are Qt based so I thought they may work more nicely. By and large, that's true. Smplayer renders better and clementine, beyond the visualization problem, seems to sound better.

However, under kde-desktop over xubuntu 12.10, clementine worked absolutely fine. I wasn't expecting this sort of problem with a simplified system. Frankly the only reason I use clementine instead of amarok is the visualizations. I like projectm. It's a wee bit embarrassing to me that the only other time I've seen it crash is a friend of mine's system, which is poorly maintained windows XP.

I'm guessing I'll be directed to sourceforge or clementine, but I thought I'd see if anyone had any ideas.

try renaming the ~/.projectM folder

any relevant messages if you start it in Konsole

look at the end of ~/.xsession-errors after the crash

Thanks for the response ... I'll have to ponder a bit, never tried running projectm from terminal before.

I tried turning off vsync earlier because I plug an external monitor into my laptop and have been running the visualizations in the larger screen. I forgot that vsync only works on one screen. It still crashed. As far as I can see, even worse.

no, just rename the ~/.projectM folder (I'm assuming that is their config settings) is too see if it's a config setting causing the crash

I looked at the /projectm folder and it contains a lot more than config settings, so I don't think just renaming it will help, but thanks anyway.

After some more looking, I think there may bbe a bug in the version I'm using. I'll try to install an older version of clementine (and figure that out ... installing older versions is about the only thing I miss about windows) or try a system upgrade.

Frankly, kde-desktop 4.9.something over xubuntu 12.10 worked better than kubuntu 12.04.

Comparing apples and oranges := How about comparing it to Kubuntu 12.10 with the same KDE version? at least do compare what is comparable, in this case the same underlying structure.
