--- Comment #11 from Marc Payne marc321@gmail.com 2008-04-20 17:16:42 --- Well, I happened to be looking at my lsmod output and noticed that Slackware loads snd_seq_dummy along with the other modules for my onboard sound. Removing that dummy module reduces the frequency of my crashes by a large percentage. Plus, Composer no longer lags when trying to play a midi file with ALSA.
I can't say that the bug is resolved, since it still crashes occasionally if I persistently open menus (quickly, perhaps 3/sec). Maybe I'm splitting hairs trying to make it crash with abnormal usage. However, it must be crashing for a reason. :)
If anyone knows of some debug channels I should use, or any other information I can provide, I'll be happy to produce it.
