lavaps crashes with the following failed assertion: lavaps: process_view.cc:207: void process_view::update(): Assertion `change > 0' failed. Aborted I've been running the same version for years and I've never seen problems until recently. Now it crashes every 10 mins or so. The two things that changed around the same time are upgrading to kernel 2.6.23 and updating gtk+ to 2.12.5-r1.

I don't think gtk has anything to do with this one. The relevant section has a comment "// hack around integer overflow", and seems to be manipulating time values.

I suppose lavaps is intimate with internal kernel structures, maybe we should ping upstream?
It looks like upstream is a guy named John Heidemann. Should we email him directly?
I haven't looked it deeply, but try with x11-misc/lavaps-2.7-r2 which includes some fixes.
I can't be sure because the crashes are intermittent, but 2.7-r2 seems to have taken care of my problem. I'll post back in the next few days if I get more crashes, but otherwise consider it taken care of.
Oops, I had another crash with the same symptoms. I noticed this time it happened at the same time as my music player (media-sound/exaile) switching songs, which causes a popup notification, but I'm probably just grasping at straws...
After some observation time I can confirm that when it crashes, it almost always coincides with an OSD popup from media-sound/exaile switching songs. Once I noticed it happened the same time as something like sending an email, which might have popped up a little status window too. Anyway, it seems to have a lot to do with what else the computer's doing at the time. Just thought I'd pass that along in case someone else has the same problem and is looking into it.
Another little piece of the puzzle: the changes are small negative numbers (-19, -24, -27, -24...). This doesn't look like a case of integer overflow.
For anyone interested, I found out for sure that it's not only triggered by displaying new popup windows. Emerge seemed to kill lavaps when finishing the installation of one package and moving on to another.
lavaps was removed from portage wrt bug 227743, so closing this too
